Toy I agree
but think it all comes down to what Jason said to sonny a week or so ago..." he REGRETS giving Mikey to Sonny" and that is how Jason views it

Think we need to "think" like Jason. In his mind , he brought Mikey into the life when he agreed to raise him. He feels guilt, regret and now responsiblity.
Think he is trying to make sure Mikey doesn't end up like HIM or Sonny.
