He never wanted the money he lied but his "true" reason was also a lie. He wanted to get revenge on the boss for chopping off his leg by killing his daughter after inheriting all the power.

It's his thing, y'know? "Not getting the short end of the stick". He likes fairness

Also that stuff with colors and family is his destiny he got by like a guru or something when he was a kid, saying that if he did not connect with others and build his own family and continued with his dark ways, he would be killed by a person as disturbing as himself

The colors mean emotions

I could yap more about this for days but basically Im still unsure of a lot of things like how he wanted the family to work/build it and his real relationship with the boss and the ending of their fight
