If you keep it after you know it's not legally yours, you're stealing.
If you keep it after you know it's not legally yours, you're stealing.
The part I'm having issues with is "taking", which is e.g. in the Merriam-Webster definition of "steal".
If someone hands/gifts you something you're still taking it (which would match that), maybe I was more thinking along the lines of robbing.
