Good idea or not, I desperately did 'chmod -R 777' to a directory. What should I do now?

I know that wasn't a "good idea," but I am working through Miguel Grinberg's Flask Mega-Tutorial and I couldn't figure out which permissions I needed to be able to run the program in its early stages. I'd been having trouble with installing the Python virtual environment and other pip stuff in a way that I can use them in non-root. Can I do 'chmod -R 755' on the directory or would that set of permissions still not be safe for deployment?

I did a recursive chmod 777 on my entire games drive and now steam can't launch anything through proton

PermissionError: [Errno 1] Operation not permitted: '/mnt/games/SteamLibrary/steamapps/common/Proton - Experimental/files/lib/wine/dxvk/openvr_api_dxvk.dll'
I was high and being dumb last night and I was frustrated with permissions across users so I just did a recursive chmod 777 to access my steam library folders between users. It worked but now Proton games will not launch.
This is the exact error I'm getting. It happens with any game that is using Proton. Not really sure what to do here. Any help is appreciated.

ELI5: Why is sudo chmod 777 /var/run/docker.sock bad?

I've read some explanations on the internet but they go over my head. Why is this bad and what's the correct way to do this if I want to be able build images on my CI EC2. Some people say use the docker group, but then I also saw this article that says don't use use it https://fosterelli.co/privilege-escalation-via-docker.html

Can't ssh into EBS volume - Accidentaly chmod 777

I was trying to recovery a classic-ec2 instance by taking the volume, attaching it to a helper instance, and then adding new ssh keys to authorized_keys in the .ssh folder of the ubuntu home directory.
I have actually been doing this for a ton of computers but I messed on one of the instances: I tried copying the authorized_keys to the mounted volume but it said I didn't have permissions.
so I did:
sudo chmod -R 777 /mnt/tempvol/ and was able to add the authorized_keys BUT when I tried to put the volume back, I get a publickey denied error.
I tried taking the volume and using a 2nd helper instance to see if I can remote into the 2nd helper instance with the volume being root, still no luck.
what can I do to fix the chmod on the volume?
​
This is the permissions on the volume in question:

In a PHP / Apache / Linux context, why exactly is chmod 777 dangerous?

Apache
Inspired by the discussion in this question, a maybe stupid question.
We have all been taught that leaving directories or files on Linux-based web hosting with the permission level of 777 is a bad thing, and to set always as little permissions as necessary.
I am now curious as to where exactly lies the danger of exploitation, specifically in a PHP / Apache context.
After all, a PHP script file can be executed from the outside (i.e. through a call to the web server, and subsequently to the interpreter) no matter whether it is marked as "executable", can't it? And the same applies to files called through the command-line php interpreter, right?
So where exactly is the vulnerability with 777? Is it the fact that other users on the same machine can access files that are made world writable?

Noob question about chmod 777 and 775

Hi okay,
I am running Ubuntu 20.04
I installed a Laravel web app to the web directory /vawww/html/example/ and need to develop using user "ubuntu"
First I run sudo chmod -R 775 /vawww/html/example/
I connect VSCode and it can READ everything fine but I can't write. Okay fine. I assume permissions are messed up.
Then I run sudo chmod -R 777 /vawww/html/example/
Connect again, and I can write just fine! Great so it's permissions. But the internet says "never use 777" so I run again sudo chmod -R 775 /vawww/html/example/ ASSUMING it's going to change the permissions back. But writing files STILL WORKS.
Then just messing around I run sudo chmod -R 700 /vawww/html/example/ and I lose all rights
Then I run sudo chmod -R 770 /vawww/html/example/ and I get them all back.
But then WHY didn't it work originally?

Accidently ran chmod + 777 on ~/.bashrc and want to revert to its default permissions. What are they?

My groggy self unthinkingly ran this on my ~/.bashrc this morning as I was adding some proxy variable scripts to it. Will this affect it from running at startup? I'd like to reset it to the original permissions, but I have no clue what they were.

[New to Linux] I can no longer access my server throught PuTTY or FileZilla after doing "sudo chmod -R 777 / "

Um, so I did a big oopsie. So I did 
sudo chmod -R 777 /
because I was tired of getting file access error in Filezilla. That broke both PuTTY and FileZilla so I can't access either of them but my game server still works and the game panel. When I try to connect now with PuTTY I get the error "Network error: Connection refused" I relies now after I've done it that it was probably very stupid to change every permission :/ Is there anyway I can revert it?
I use oracle cloud if that makes any difference. Any help welcome!

Instead of doing chmod 777, what should you do?

I did that whenever I had issue with Apache not running when doing sudo service httpd start or not being allowed to dump a file on WinSCP as the centos or ubuntu user on a AWS instance, but now I know better and I want to know what command to default to. Do you need to run it as the centos or ubuntu or ec2-user?

*NOOB ALERT* May someone please help explain the permission system for linux? I dont understand why chmod 766 doesnt work but 777 does.

my system- manjaro kde, kernel 5.13.19-2
an image to better describe my issue. https://ibb.co/CBd77hP
I freshly formatted a new SSD thats mounted to /run/media/"myusername" the permissions are currently set to drwxrw-rw- by doing "sudo chmod -R 766 madrive" madrive is the ssd.
Problem is when I go to open this up in dolphin it says "Could not enter folder /run/media/cariga/madrive."
this is what I get when I do ls -l
drwxrwxrwx 1 cariga cariga 16384 Sep 25 17:13 backupdl drwxrw-rw- 3 root root 4096 Oct 8 12:11 madrive dr-xr-xr-x 1 cariga cariga 2048 Sep 27 15:47 MANJARO_KDE_2114
Im a complete noobie and im learning but I thought 766 means read write x to owner, read write to group and read write to other. If read and write allowed to other how come I cant browse it on dolphin? Or even terminal for that matter. Doing "cd madrive" gives me "cd: permission denied: madrive"
Funny thing is doing "chmod -R 777 madrive" completely works!!! Trying to wrap my head around this I just dont understand. I thought execute means executing a binary so why would 777 works and not 766?
May someone please help im trying really hard to understand linux.
