I'm going to claim my friend as a dependent and use the return for bills/debt
Why are you claiming him as a dependent?
He has been making life difficult for me, I want to use all his money on credit cards.
It is wrong to lie on your taxes.  Plus, you are the only one to get in trouble, not him!
Why, I have been playing with him for years, it's not like your government could get me in trouble.
Because the government does verify the things you claim on the taxes sometimes and you could get found out. You should never lie on your taxes, you might end up owing money or going to prison.
