Like it or not, but telling a player his PC has to behave in a certain way just because the DM wants him to (whether justified or not) is generally among the worst mistakes a DM can make.
Stay out of this and let the other (living) PCs handle him. Assuming they don't agree with him. Either way, you really should accept the party's decision.
