He was a bum in the recent arc aswell!! Hell, REI was the first to apologise to Touya, and she didn't even do anything wrong! While Endeavor's plan seemingly was to double suicide with Touya without even having any meaningful conversation with him
I can't believe there are people defending him
His son fucking died. Accidentally killed himself when the trauma he went through made him lose control over his quirk. And all Endeavor thought was how unfortunate that Touya wasn't the perfect creation
