You're smarter, and more worldy now.
That's all that's changed.

The thing I don't understand about Tom is... "Oh so there's a better version of me out there, who is unfortunately in a fantastically dangerous situation that he might die any moment, but I am going to help you destroy (overwrite) the universe anyway and kill myself in the process rather than try to make a go of the life I have now, because it's some how meta delightful that there's a copy of me who thinks I'm scum just like you think I'm scum, so I'm just going to bend over and accept that if you say I should kill myself for his sake, and that I should take the universe and everyone in it with me, except you."
That's a seriously *&^%ed up sort of Muppet who needs to be put down.
Hells, bells, and it's exactly what's happening on Dexter at the moment with the Doomsday Killer.
Reminds me of Emperor Catagia a little too. How he thought that he would turn into a god off world when he planned to allow the Shadows to destroy Centauri Prime.
