>>123320018Because King hates his dad. No, seriously.
See, King is the kind of mongrel that on father's day, one of the few times western world maybe considers fatherhood important, tweets "let's also remember single moms today". See, his dad left him and his mom.
And King hates dads. So, all dads have to be good.
Thomas Wayne being a flawed, broken but ultimately good person in flashpoint? Nah, he's a villain now.
Bruce having had progress with the Batfamily and Damian?
No, he's a shitty dad that's all about his catwaifu now.
However, Alfred is the best comicdad. Alfred's awesome and no one can doubt that. He did great. Legitimately great, he's proof dads can be great.
So, King killed him.
Because King doesn't like good dads.
