He is Eros and he's Apollo
Judas is, surprisingly, very polite and kind to others, though he can be a tad immature at times. If there's room for an inappropriate joke in conversation, you bet he'll be the one to take advantage of it. He's a tad self-absorbed, but it comes with the territory of being so damn pretty.
I mean. Seriously, guys.
As for relationships, Judas loves to make friends because he likes to talk. And talk. And talk. He's a hopeless romantic with the heart of a performer, but at the same time, he isn't looking for anything serious. He's a bit of a man-eater.
Judas is an Id without an Ego to keep him down.
He is the libido and dreams of a dead dead man.
