By " His Fate" jendi Toad means of course...

that michael sails away on the motor boat ( like when we last saw him). He gets about a mile away and Walt's eyes turn deep red and he pulls out a gun and shoots his father.

I think its fair. I mean he deserved way worse... but his son being turned into a dharmist robot and then assasinating him just as micheal believed they had a new begining. now thats fair.

Cuz all michael did, he did for his own selfish reasons, and called those" walt". But really it was for Him "being a good father". Its only right he should not be allowed to enjoy any of what he did so many bad things to create.
