I try to avoid killing random people in video games. Dunno why. Would I get upset if I could murder kids in a video game? forget no, seriously, who cares. Nothing breaks immersion more than shooting a human being in the face with a rocket launcher and they just shrug it off because "muh moral compass". I mean why is it more wrongful to kill a baby than a grown man anyway? Because they're weak and defenseless right? Where do we draw the line at what's strong enough to kill in video games? Pretty sure ESRB is a total bitch about this kinda stuff though, and it'd make it more difficult to sell the game.
It did feel sorta weird burning tons of mutant babies to death in The Forest, though. Maybe because they were literally infants. But they were tryna kill me, so I had to immolate them.
