I used to be an art thief.
Really? Why would you steal art?
I was pissed off being so poor as a kid.
Being pissed off doesn't give you the right to steal. Imagine working for something and someone just takes it from you for no reason other than wanting it.
I was desperate and greed always wins.
There are other ways to make money if you're desperate. Stealing is wrong, so you could have done odd jobs or started a fundraiser to make some cash instead.
