emotional empathy

Most are only capable of visual empathy.
Ie they would not want to see a starving child.
But if you say 'sign this, you get 100 million monies and 1 million will starve' ppl would sign.

Everybody does what they do with good intentions in their mind.

I don't think that at all, ppl thinking of other's wellbeing as if it's some fancy luxury even when said ppl have more than enough or more than others (in some cases it is a luxury, but not really nowdays).

Hate is so easily weaponized bcs it's there, it's not reinvented, it's used (often not even the topic/subject of hate is invented, just reused bcs it's cheaper & more effective).

If that (the quote) would be the case then ppl would also try to correct when they see their "good intentions" aren't doing good.

People are used to call others "evil" when they're not included in the target group of good intentions.

No, that is just the selfishness I'm describing above - calling someone evil bcs their actions don't benefit you is just preemptive opportunistic behaviour at best (and there is a lot of this, almost the default).
(I say this if "good intentions" are actually good, not like a money grab or killing or whatever.)

I prefer to judge people by other factors than the abstract "evilness": empathy/psychopathy, generocity/greed (or rather selflessness/individualism), agency.

Yes, "evil" is one of the possible end descriptions of the above process (with many more factors). Starting by saying someone is evil would be weird/hurtful/baseless.
And all of such factors are very time and culture dependant, can't have it otherwise, it's not science.
