I feel like between the idea that 1) every life is valuable and 2) sometimes things are better if a particular person dies, there is a synthesis and recognizes the truth of both statements.
But in this case I just hope that Warren is okay. I imagine if I’d killed someone I’d be thinking about that time I killed someone on and off for the rest of my life. My idea of how people might react to these things obviously may not apply since Warren is a person, not a statistical amalgamation of likely traits of a person. But Magnuson might not be done causing harm in the world just because he’s dead.
