In my opinion indexing ones positive or negative impact like this along 1 axis is courageous but fraught. I'll attempt explain why. On the one hand it's a useful exercise but can turn into solipsistic culdesac. It's a subtle distinction but I believe that impact is actually created in the relational space between beings and beings with their environment but this is difficult to articulate in our ego centric culture that wants to worship or vilify the individual and the self. Thanks, curious to get your feedback. .David r Hawkins levels of consciousness has a model similar to yours. Although he uses a logarithmic scale and believes a person can only move a few points in a life time. Ps what are you thoughts on Christopher hitchens work on mother Theresa? He thought she was a psychopath who did a lot more harm than good. I don't know personally but I think it does highlight the danger of idolising the individual
