Yes. unlike Michael, Vito did accept himself for what he was. But I can't see Vito simply sitting back in his old age and saying, ""Hey, look at my boy Michael--he's helping to feed the starving Africans...and he raised the minimum wage." I don't see him walking away from the rich empire he created through gambling. He had to have a plan for Michael to help transition his empire to legitimacy--and continued wealth.
Michael came to a fork in the road with the Solozzo killing. In spite of his denial,I believe it WAS personal,not business.He had a choice, either take the path to upper world legitimacy,like Vito wished for him,or enter the Family "business" Once he did the hit,there was no turning back,and I believe he knew this. His life would forever be changed..Vito realized this as well, hence his reaction when told that Michael killed Sollozzo. At that moment,all of Vito's hopes for Mike went out the window forever,and he sadly realized that Michael had achieved his "one destiny".
