I think some people project a lot of their own experiences onto Gale when he is 100% supposed to be an insufferable wizard who needs his ego taken down a peg or two or three. The game teases him because part of him thinks (or wants to think) that he is hot shit. But that is also why I like him. He is an insufferable, cocky wizard, but does have a heart under all that. I believe he can live a good life when he's not chasing unattainable dreams or women.
Hence I do disagree that blowing himself up is a good ending, but I think the writers were going along with what the interviewer was saying rather than making a statement.
I find some fans of Gale don't see the man's astronomical ego and have been complaining about people "being too mean" to him since EA. I just don't want all the hubbub to encourage Larian to make Gale as much of a "poor me" baby like some fans think he is.
