What you do and also what you don't do (but could do) will always be good for some and bad for others (neutral for the rest). In that sense there is no "force for good", only a good for: Yourself, a specific group, the majority, etc.
Now, I have also pondered about this topic of doing altruistic work full time one day if I get the chance and it is nice to see a discussion (even just a small one) about it.
I don't really fear regretting it afterwards as the attempt also counts in my opinion, as long as you don't accidentally cause more harm than good in the process. In that sense, wouldn't you instead regret it to never have tried it if you could have?
