Delusion + power + conviction doesn't always equal evil, so there has to be something missing in that equation. I'd wager it's evil.
I think the missing ingredient is simply not caring about the outcome. It could be because they don't have empathy (sociopaths), or that the society has trained them into normalising obedience to the cause (facsism / communism) or inhumanized their targets (consentration camps).
Acts can certainly be described as "evil", but I don't agree that "evil" is some type of force that affects people.
To go back to my original point, the simplistic equation falls apart if you spend a second looking for counter examples.
Sikhs give free food to any who asks, without expecting anything in return. They are deluded (they do to it please god), and need power and conviction to do so.
I was thinking of the human consequences. In my language they are almost synonyms.
They of course care about the outcome, but not the effect it has on the target group
It's strange how one can normalize cruelty. Just think of how prison rapes are joked about in media and movies, as if it is an accepted consequence of committing a crime. It is a cruel and evil act that many choose to simply ignore because it is so common
