Let's say, that it's enemies' tier list. The biggest enemies(for example murderers, who killed your family member) People, that you hate a lot(archrivals, that are arrogant and don't respect you, through your whole life). Mid-level enemies(someone, who makes fun of you, however he/she is not your main enemy. It only apply to people, who don't respect your path of life). Would you sacrifice mid-level enemies if you had a chance to advance at work or win during the lottery? By sacrificing, I mean ruining life of that person or letting him/her die(not helping, when that person would have car crash for example).
