Ethical Dilemma

Should I tell this guy his fly is down? Before you answer, I should mention he’s a serial killer. An ethical serial killer; he only kills unconvicted murderers, corrupt cops, etc. But he’s no saint; he profits off our corrupt private prison system...as a way to seek revenge for his unjustly incarcerated dad. Don’t judge yet; he later killed his own wife! Who begged to die; she had terminal cancer…from the chemicals he exposed her to nightly. Since they had to live next to a uranium mine to keep his otherwise world-destroying superpowers repressed. Not so straightforward, is it?
