Judas (how I see him anyway)
I am not religious at all, never even read the Bible. But the story of Judas and Jesus just intrigues me so much.
Think about it:
You personally know someone who is more or less divine, maybe you consider them a friend, a leader or a confidant, just someone who is supposed to know it all. You follow them.
Then something changes one day. You don't know what exactly. Maybe you were blinded by greed for a moment, or something terrible possessed. All you know is that doubt has set in and you'll betray them.
Your friend tells you and bunch of other people they know that they'll be betrayed. What do you feel? Guilty, terrified, anxious?
You betray them, with an imitate gesture, a kiss of all things. Address them as someone above you, and it's gets them caught.
It's come to light that your friend is going to die as result of your betrayal. You might feel it all sink it, try to repent your greed and change what has happened, but you can't.
You take your own life.
It doesn't help that I'm a sucker for betrayal stories, and I just think Judas is very interesting.
