Honestly, you are right.

Sitting on the Internet I would love to say you should find his console, sell it (as it is after all now yours) and use the money for the tickets.

Sadly, you are right. It is important to do the right thing and be better. It really sucks that not everyone is, but if everyone does wrong then the world will just get worse.

The best thing is to learn the lesson that there are horrible people and avoid them. I am just sad for you that these are your family and you can't get away from them yet, I hope one day you will find better people to spend your time and attention on.

But I would still recommend some revenge if you can, even is it doesn't go so far as a crime!
