Thank you for both correcting it and answering anyway, that's not a given on the internet :)

I suppose I understand. It's a denial of philosophical realism (he wouldn't do that bad thing if it wasn't for me and therefore I'm part of that bad thing) in favor of idealism (no matter if I want the bad thing to happen, he shouldn't do it). I suppose I hold that same opinion when I advocate for intervening in the market to limit the supply of "bad stuff".

I can respect that.
