Vito's ”Who says you can't live your live exactly as you want to live it?" no doubt applies to husbands only not wives

I reckon it is not complaining or blaming their parents It is not interfering, it is parental guidance

How did he spend time with his family? Every scene Vito was seen with them was business apart from Connie's wedding

Sonny's philandering, Connie's bad choice of husband, Carlo's wife beating, Fredo's sexual excess, Moe slapping him around all went undisciplined

If Sonny was alive he would have become the Don even though Vito knew he would be a bad Don
Fredo was left rudderless

The only child who got guidance was Michael that too to make the Corleones top Mafia family again, leaving him a murderous legacy apart from the loving father mentioning his happiness and his son

Vito's action, inaction and slip ups adversely affected every one of his children and his son-in-law including violent deaths
