Senseless decision making.
Violent.
Doesn't trust many people.
Merciless, sometimes he even enjoys killing.
Angry most of the time.
Impossible to calm.
If these were Sokka's character traits, or Toph's, or Aang's, would you have believed they could form friendships and be effective partners? You have not indicated at all that there is anything likeable about Eidos. Nothing. You used those six phrases (and "hot headed") to sum him up as a human being.
Your character is going to be defined in this RP by his interactions with others. How will he interact with Taru and the teachers? Because if he is belligerent and violent, I don't think the group is going to like him very much, and that's going to lead to you being ostracized (because no one except ScrubMage will want to write with you) and probably leaving the game.
EDIT: It's not a very good character. His nature is not justified. No one is going to trust him, no one is going to want to fight by his side, or save him from danger, or any of the things groups in group RPs generally do.
EDIT 2: The point is not that no character should be angry. It's that all the characters should be reasonably realistic within the setting. It isn't realistic that he would be chosen to teach the Avatar.
