I would agree with the general sentiment that the writing as it regards Pete is pretty weak. As others have posted, ignoring the behavior, exiling him, and killing him are not the only choices in Alexandria. (Perhaps those might be the only choices outside the walls, in the wild and on the move; but the whole point of Alexandria is that other options exist.) All of the other choices (esp. listed by Quentin) seem valid. Make him stop (take away the alcohol, physically separate him from his family, etc.) and if he refuses to provide medical treatment for the community as a result then beat his ass. If he still refuses THEN take more extreme measures. You don't have to jump to the nuclear option as your first choice. - Walter.
