i immediately think of the inverse. spoilers for very old games.

consider Shadow of the Colossus. admittedly, it's been a while so i may be misremembering some points. but, the premise of the game is you play as a young man intent on reviving a sacrificed girl; he is a mute named Wander. giants roam the land ('colossi') and, from the start, Wander is tasked by a disembodied voice to slay these colossi to revive the girl. as you ride horseback through the land slaying these colossi (who are just wandering around peacefully): the colossi fall with exaggerated groans of sadness, the land becomes a little darker, and your character's appearance changes somewhat. it's revealed that the disembodied voice is actually a demon who was ripped apart and scattered across the world (or something), and these colossi seal the demon's disparate parts. by the end of the game, Wander has slain all the colossi and revived the demon, and consequently Wander is seen a demon himself and sealed. the demon kept to their word and revived the girl, however.
a shorter example, in Oblivion there's a Fighter's Guild quest in which you're tasked with infiltrating a rival guild ("The Blackwood Company"), and during this quest The Blackwood Company drugs you up with the sap of a hist tree and tasks you with "slaying some goblins that have taken over a village." you slay the goblins as they request, but after the drugs wear off you it's revealed that you slayed an entire village of innocent people; the hist sap only made you see goblins during the act.
i like these examples of games subverting your expectations and turning you into the villain. it's a form of empathy -- either feeling "sorry" for the character, or inversely: thinking they're a fool and thereby feeling like a fool yourself -- but it's more visceral because even the player is not in on the joke until the computer game reveals it to them.
yes, it is. for sure.
