Speculations on ME3 ending

[Magic McKinley]

I don't know about you guys but I found this pretty awesome. So I was talking to my mom about the mass effect 3 ending. she never played the game but understood that the endings were basically the same and brought up the topic of pre-determined end. what if mass effect 3's ending was one big metaphor for no matter what you do, you have a pre-determined end and that is how you will go? Time to speculate.
