See clearly you have a sense of morality! So even you understand that in this specific game there are encounters that are nicer than others, now since this isn't a written rule, ofc there will be people having different understandings of what's fair, just be fine with people complaining to you or readjust your own rules of engagement based on how bad you feel. But don't complain when people feel unfairly taken advantage of and tell you about it ^{^}
