Some times yes. It is.

In Superman's case he will kill if it is a mercy, however since he is so obscenely powerful it's not surprising he thinks he can find some work around to killing. Killing isn't off the table for Superman, it's just last resort, and since he has so many powers, that's a lot of resorts prior to that. Aang is a Buddhist 12 year old, of course he is terrified of killing people. Being angry at him for it is like being angry at a kid for not shooting a guy who broke into his house even though he had a gun in hand's reach, he's a kid. Batman is just warped, he has a phobia of killing. And Goku is a Sayian, he is hardwired to want to fight things, he spared Vegeta cause he wanted to be able to fight him again someday and that actually worked out for him, he is not going to pick and choose when to follow that instinct and when not too.

There is an inverse though, see Unohana doesn't like killing things either, not because she doesn't want to hurt people, the opposite in fact. Like Goku Unohana wants to be able to keep fighting, but unlike Goku she can heal someone's fatal wounds, so she brings someone to the point of death, undoes it and then starts over again in new gloriously bloody ways. So there is some food for thought on the subject.
