In his first appearance he claimed he was adopted by Prof Dawson. Imagine if that was true, that he wound up in a loving family. Imagine the take your kids to work days, speaking like Ash when he explained the math issue
thing is, this man has similar feelings as ash, apart from the sa, he had to see his family die in front of his eyes, and likely so much more, but he doesn’t have anyone for him to vent to, he doesn’t have anyone who can help him. he probably envies ash and eiji, because they have what he doesn’t have, a bond
Pretty sure the sa too, his brothers are super creepy around him and he was presented as a s** toy to Dino and his unbothered reaction to it implies that it's nothing new for him
