After Sojiro's duel with Kenshin, he realizes that his belief that the strong will live and the weak will die wasn't the truth

He felt broken as his emotions weren't suppressed anymore as he screamed and cried out of frustration and pain, his whole world collapsing in front of him. This wasn't how he expected it to be it was supposed to be completely different

"AHHHH! This isn't how it was supposed to go..." He sobbed as he banged his head against the wall, knees pushed against his chest
