Release he did "do everything" for his kids.
I think Rex is trying to say he did not do everything for his kids.
It is obvious the man provided material things and entertainment outlets.
He failed to instill the value of hard work and the resulting reward of self esteem, self worth and self sufficiency, for a job well done and reaching a goal.
Those kids are lacking the most important thing (after basic needs) parents can "do" for their kids.
Teach them Life skills.
