The first two types of people are not who I'm curious about:
1. those who mean to harm others and do so
- these people are just about universally considered "bad"
2. those who do not mean to harm others but do so (e.g. a young / poor driver getting in an accident that leaves someone else dead)
- people are largely divided on this in principle and especially in specific cases

I am curious about:
3. people who mean to help others for its own sake (or without any obvious personal benefit) and who may or may not achieve impact at a massive scale
4. those who help others - and may even do so at a massive scale - but only when doing so helps them indirectly
