Tanjiro was a very kind guy you admired him more than anyone in the world even after his family was massacred by the demon king himself he still wanted to defeat Muzan and when your family died you just wished you went with them

Some people could take it someone people couldn't and you knew you couldn't take it after you defeated an uppermoon with Tanjiro you put your sword through your stomach

"What the...how...just hold on! Kakushi's will be here! You didn't mean to do this, right?"
