No one ever believed Jets 'change' It's absolute bull crap, go die in a hole fascist communist nazi jet *ahem* sorry I don't know what overcame me there. Don't do jet kids.
Yeah, I think that by 'killing jet' the makers thought they could redeem him, like if he died for a good cause, but some people are just too bad to be redeemed. Also, they do make a great joke about how confusing jets death is later XD
Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did. So throw off the bowlines, sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. — Mark Twain
