i mean, he
did get pissed tho. I'm not sure what else you expect, given that there's two walking natural disasters under him, but it's not like he at this point has the ability to fix up an entire town snap crackle pop.
To begin with, it's closer to a village than a town, but translation artifacts and what not. Considering it was the farthest-out wasteland base, there was almost certainly <1000 and given the fact those two could blow it up with a rampage most likely <100 people there, and we don't know how many booked it when they heard the combat or were out in the wasteland adventuring.
In other words, in terms of people actually killed, probably only a few actually innocent folks were caught in the crossfire, and the rest were criminals involved in sex trafficking, scams, and racketeering. Death sentence? a bit harsh, but...
considering he could literally blow up all these bases himself with maybe one max power arrow or two each, he's not exactly being harsh or brutal. Though yes, putting that as "gentle" is a bit... Well, he's more "Restrained" than he is "gentle."
I feel like there's a translation artifact. In terms of being soft, he's absolutely being soft. but in terms of empathy we talk about absolute value, so "empathize" looks like it fits but is anywhere from hilarious to confuzzling in context.
