This is something I loved about Hitman. Theres a bit of set dressing appeal around violent infiltration, but by and large, 47 uses social manipulation, knocks out only a few people, and only kills his targets, who are terrible people that make the world worse.

It also has a nice quote in a cutscene. (Paraphrased)

“We don’t take sides. ICA always remains neutral.”
“I hate to break it to you, but neutrality is a side. It’s the side of the status quo.”
