Ken says what I'm thinking, as is often the case. Spam bad? Yup. Davidson a scumbag? Yup. Happy about a murder suicide? Nope. Happy about just the suicide? Nope, never.
All I can say is, if you can crack jokes about this guy killing himself and/or others, then you've never had to deal with the aftermath of a suicide. It's horrible, it's gross, it hurts you, it chews you up, and you never forget it. It's not something I would ever wish on anyone, worst enemy or not.
