Wheatley broke my heart when he betrayed me... Not like I didn't suspect it might happen, but I hoped it wouldn't. I don't care if he tried to kill me, I forgive him anyway! HE DIDN'T MEAN IT. HE'S JUST A BABY!!
and I actually don't think Wheatley was intentionally stabbing Chell in the back, I think being mounted to GlaDos' body made him corrupt and evil, because being taken OFF her body and put into a potato made GlaDos nicer, while making Wheatley evil. The body was corrupt because Aperture fails at everything.
it wasn't wheatleys fault at all! i blame glados! she was being a jerk to him when he was in charge! but then again, i take that back, i blame the creaters of everything there! they made everything have an evil side!
ex: the turrets sound so nice and sweet, then you turn the corner and they shoot you down! o3o i mean really. why would the hurt us like that?
