Presumably you knew that before you stepped into the teleporter, so decision to partially die is in both copies of you. This all assumes a destructive copy process -- if a non-destructive teleporter is possible, you don't need to destroy remaining copy, but all kinds of legal issues arise. Maybe you'd want to have one copy destroyed to avoid paying double for lunch.
