I was wondering... Is it coherent that the first predator who got captured slain the marines at the beginning, but initially wanted to "defect" ? I understand he got his equipment stolen from him and that must piss him off, but it's part of the risk coming on earth in the first place I guess. And maybe his motive change throughout the movie, but if he's going on a killing spree when he escape, (which is likely the case from what I've read), even if it's stargazer men, don't it seem a little counter productive for him and the humans in the long run ? I mean if he really wants to defect, he can't be that deadly without consequences, can he ?
