Vito never wanted this for Michael yet Vito coached Michael to be the Don

Vito planned all the dirty work, killing of Carlo Rizzi and Moe Greene, the baptism murders for Michael to carry out after Vito's death thus leaving a murderous legacy for Michael

Vito could have handed the family business to Clemenza & Tessio and let Michael try to start a new life, away from this

Well, Vito had the choice to let Michael go and live his life, even a political career [if may still possible] away from this but dragged Michael into the crime business anyway

What was really Vito's wish for Michael indeed
