Why is a trashed email still in Archive Folder?

See this thread How to permantl delete messages from Archive in OSX?

If you create a folder on my my Mac section in mail side bar and create a rule that all incoming mails should move to this folder , it will follow .

And you delete the mails From this folder to the trash , they will move to the trash of your gmail account see this article Delete or recover deleted Gmail messages - Computer - Gmail Help

The trash mails can be still saved permanently for sake if you want to read them later , create a second new mail box and select them ( command and A ) , copy them ( command and C ) and paste them ( command and V ) over the folder .

Archiving in web mail is just labelling , they cannot be deleted but can be stopped showing in apple mail application ie . Archive folder , by going to labels in web mail account , and uncheck the box of show mails in IMAP .

Also you can not delete the mails from archive folder of apple mail application , its just a configuration from web mail account to apple mail application ( kind of mirroring ) .

I went to Gmail, and there is no way to turn off this action.

There are settings in Apple Mail / Accounts where behavior of the account might be the key, but it is confusing. The preferences acts like I should try to keep copies of everything, even trashed. If I trash something I want it GONE.

There is nothing in Mail to change Gmail's behavior. They keep all of your email in order to sell you. Don't be Google.

Look in the Forwarding and POP/IMAP tab.

Here is what I set to change the behavior to make it delete emails that I delete.

If it is a Gmail account, you have to turn that off in the Gmail settings on its web portal. Gmail does this by default. If it is another provider, I don't know what might be causing it. It isn't a Mail feature.

Google makes it particularly inconvenient to make deleting emails so that they are “gone” for the reasons Barney-15E explained.

Mail does not do that. If you want to be certain no copies of your emails exist after you delete them then perhaps Gmail isn’t for you.
