bipolar pill, crazy pill whateverNero, from what we have seen , is not bipolar. On what grounds to you base that?
the point is nero is chemically unbalanced in the head.
Yes thaey are different - Nero has believable even logical grounds/motivations for his actions. He sees the Vulcans and by association, the Federation as the agents of his suffering through Spock's/The Federations actions/inactions/poor timing.
Freud: "aww classic transference"
How pedestrian.
Shinzon doesn't - his actions are against equally innocent & wronged parties (Picard & The Federation) .
His obsession with Troi was just sick.
Aww yes Shinzon is a more complex character, atleast his not insane in the membrane.
And I do believe your crush on Troi had biased your opininon of shinzon.

But that scene just made shinzon seem more human. Shinzon is a human boy that growup around aliens. He had never seen a human woman, shinzon's sexual fantasies towards troi is only understandable.
He sees someone is better than himself, so to fix that he must exterminate him and his entire species? Are you for real?


Nuff said really.
