Now another thing he's upset is that all new characters start at 2 levels lower and feels that he's being penalized for the party complaints as opposed to the party who thinks that they've been penalized by having that character around as long as they did.
I hate it when D&D becomes like Survivor with eveyrone trying to pitch their story.
First, on choosing the domain of healing - it could be just so he can heal better on himself, or reduce the number of spells he feels he has to cast healing. Choosing healing domain does not come with the baggage of HAVING to heal everyone whenever they need or want it, it just means you are better at healing when you choose to do it.
Okay, let me be very clear on this next one, highlighted by your comments in the quote above. You are totally unfairly punishing the player (not the character, but the player) if you require him to start two levels lower BECAUSE THE OTHER CHARACTERS KICKED HIM OUT.
The whole reason you reduce the level a new character starts at is to prevent them from being foolish and just getting themselves killed for the fun of it. You want them to invest themselves into the game, and care about death, and not just change characters whenever they feel like it.
However, it is totally different if this player wants to continue playing this character, but the other characters kick them out. That isn't an issue of a player seeking careless death, or not investing themselves in the game, or just wanting to change characters on a whim. This is a scenario which you, and the other players, are at least partially culpable in bringing about. He just role played his character the way he felt it should be played. Others did not like it, and so kicked him out. You don't punish him for playing the character that way by not only REQUIRING that he start a new character despite the last one still being quite alive and kicking and wanting to continue playuing, but then reducing that new characters levels in addition to kicking him out. That is just plain silly, and vindictive, unless you think it was this player's intention to drive other people to kicking him out just as an excuse to start a new character (and it certainly doesn't sound like that).
This is starting to sound like a DM issue, in addition to being a player issue.
