I'll add something to this that I think is important: "on purpose". Accidents are terrible, but they're not evil. Accidentally hurting a child by stepping on their foot isn't evil. Purposefully stomping on the foot of a child is evil.Harming the innocent/children is evil.
Yes, they can disagree on "things". Not on "is genocide/child abuse/murder of innocent people a good thing". If you disagree with that, you're not "reasonable" or "decent".In fact I can think of things immediately which would fall under this scenario, and that is the point. Reasonable, decent, people, can disagree on things.
