Can I take my friends videogames and sell them because he owes me $1000 and is too stubborn to pay me back?
Are you serious? How will he respond to you selling his stuff without asking him first?
He's such a terrible person and I really don't care what he does.
While it's understandable to want your friend to repay the $1000 he owes you, taking his stuff and selling it without his permission is not the proper way to handle the situation. Selling someone's stuff without them knowing will get you arrested.
I won't get arrested. I can sell whatever I want for whatever the price I want since he's a terrible person and I just want to get back at him.
You will because it is a crime to sell another person's things without their consent. You will also lose his friendship.
