^^^Yes. I think real life characters like this tend to inflict their rationalizations about how what they're doing isn't wrong or even is necessary for other, higher purposes. Or rehearse the supposed wrongs of their enemies which they are righting or avenging.
Villains with ideological motives in particular would be eager to justify themselves. However, these characters are almost never allowed to have their own point of view. In fact, they very often don't even get to be allowed to state any motive at all. And the scripts almost invariably ascribe a very personal motive. In real life, the only example of such a thing that even remotely approaches this that I know of is Lenin, whose older brother was executed by the Tsar. The scripts don't seem to want the slightest possibility of the viewer misreading the villain as misled rather than baselessly malicious.
And the characters who are supposedly motivated by their grudges are rarely to be found. They certainly are not to be heard reciting their complaints. In fact, the scripts almost invariably merely show the villainous character's envy. The villain rarely makes any charges against the protagonist or even the victim.
