Well, it depends, and I know we're being purely hypothetical but in order to want to do something good for the people, you'd at least need to be surrounded or have an interaction with said people.. and gain some feedback from them and what ails them, so you wouldn't be alone per se. Although, one always runs the risk of determining the needs of others, and that, as much as one might tell oneself, is always self serving.Yeah having a network of individuals is really great, they can always help you to see the things from another perspective and cover those "blind spots" but what happens when you're trying to do something good for the people but you don't have a group of people that can tell you all of these things so you can be aware, I mean the good guys watch over you somehow like a "divine" intervention if you will? because you're not trying to gain power or control people, you want to help or you just have to deal with all kind of attacks from the bad guys but if you're not aware then what? I know that the good guys can't intervene directly right?
Two, this is where I think some personal work and faith comes in place, I think one has to remain open to trying things out, and having the initiative to work towards the benefit of someone else, but should be able to recognize when the fruits of one's actions are presented. Reality itself can serve as a feedback mechanism, and if one does something with good intention, but that ends up harming someone else, it will be visible eventually, and responding to that kind of feedback is crucial.
But again, that is tied to self awareness and self work, because in such instances, most of us would probably double down and carry on, ignoring reality.
So, it's difficult to say really.
