From my memory I didn't think mangekyo was awoken by simply the death of a loved one, was it not necessary for they themselves to be the killer, or at the least shoulder great responsibility or guilt for the victim (who may or may not have also needed to be an Uchiha) ??
@Saitama-Sensei My favorite manga is Hakaijuu, Dorohedoro, Starving Anonymous, My Hero Academia, and Beastars. I love both the artwork and their stories. I'm also a big fan of Junji Ito's work.
@Lucki_gal_ Sir you don't have to mention the age. We still can recognise by the text you have given. Brother when you get older and the hormones starts to kick in you will find out. Good day 'sir'
