I mean, the thing that you have to take into consideration is that a (unfortunately) large number of people always react negatively towards any main character, or even sub character, that isn't immediately bloodthirsty ruthless and immediately and only resolving problems through violence. They assert that any act of diplomacy or sociopolitical move is weakness and any act of kindness is heresy.
The number of times I read the comments of manga (Isekai or otherwise) where the MC reacts with something other than immediate murder or torture and they freak the [bleep] out is nearly immeasurable. It's, frankly not only disturbing, it's disgusting.
Hell, I have had to explain on a number of occasions how the (apparently) expected response would ultimately lead to the either immediate or very rapid end of the manga. Such as: MC immediately responds with violence; regardless of murder or not the local authorities try to arrest them; MC again responds with violence; the national army tries to eliminate them; the MC responds with violence; other countries band together to eliminate them; MC responds with violence; all sentient beings in the world are eliminated (not conquered, eliminated); the local God(s) finally take action and try to eliminate the MC, who responds with violence... Universe ends, MC dies. End of manga.
Or, worse, MC responds with violence, local and national authorities decide that those MC cared about are also a threat and eliminate them while MC is busy murdering... MC therefore becomes responsible for the deaths of those they would have tried to protect, because they responded with violence as opposed to trying literally anything else.
But, no... violence and "alpha male" MC is all these people want...
Please note, this, as a whole and in its totality, does not (necessarily) represent the person you responded to, but their comment still reads like those "others."
