However sound your epistemology may be, this feels like unhelpful gatekeeping. Saying a one line disclaimer "That doesn't mean that trying to help people is bad" falls flat when you spend the entire article constructing a special category of personal failure for people who fail to effect change: "moral incompetence". This doesn't help anyone learn anything except that apparently if you fail, it might be because you didn't actually care about succeeding in the first place! Your failure likely involved concrete issues that can be learned from and changed, chalking it up to "oh well it turns out I was the problem" is an unproductive take-away and only serves to discourage people who can't or won't have the right intentions as you define them. Let's leave the mental purity tests aside, modern society works because people have the space & incentive to do good regardless of their intention.
