I was watching episode 5x14 of Lost. Faraday comes back to the Dharma compound and asks help to go to the others to talk to Eloise. Him, Kate and Jack manage to get to the others's camp, but the way he handles the situation is so out of character that it makes me think he wanted to commit suicide.
Being the nerdy character, he storms in the camp, pointing his gun around asking to talk to Eloise. When one of the others try to reach for his gun, he shoots few bullets to warn him. Then Richard comes out of his tend and he points his gun to him, asking for Eloise. Then he even starts counting down from 3 in a threatening way still pointing his gun to Richard. At which point Eloise shoots him to death.
Given that in his previous encounter with the others, he was able to convince Richard, very peacefully, to lead him to the most dangerous thing on the island (the hydrogen bomb), why was there this sudden change of tones in this episode.
Why would he act in such a threatening way? Was he intentionally trying to commit assisted suicide? If so, why?
