There's a conversation with Spike when Angelus returns and he sides with Buffy to destroy him, series 2?
He describes people/humans/mortals as "McDonalds happy meals walking around" so why would he want them destroyed, why would he even dislike them?
You can work with that, immoral though it maybe, if the character is attractive enough to get away with it.
And though it's shallow, charisma/looks/sex appeal/entertainment is the key.
Hexaat lacks all that, so why would you put up with her?
Of course it's all balony, I said a while back, Spike was the one who really destroyed the vampire myth.
He was stunning and made you laugh and.......... was a merciless killer.
Well we all have our faults so that can be overlooked.............?
The "initiative" nonsense was created to deal with the character they created which made no sense whatsoever in the Buffy world but the public/viewers adored.

Luke did have training: he used to shoot womprats all the time back home, and they weren't much bigger than the target on the death star.
Similar arguments can be made for every example given.
Defensiveness tends to boot objectivity out the door.
