I think of it as the food I must eat.

I am to hunger and I am to eat, I am to end something’s being in order for me to be.

Best I can do is reduce the damage I induce. Eat just enough and waste little. Regardless I did an evil and now that something is no more.

I must have reverence for the harm I induce. To apply this into politics, harm will always happen - best you can do is fixate on the interests that are dire and do your part to reduce the harm in other avenues. The world is so interconnected, that almost every action has a negative - we are often just oblivious for we can only see our part.
