Young remains in the right while Rush is almost always in the wrong (even though he's probably the most logical and clear headed guy on the ship- I guess using logic makes you bad on SGU).
Which is actually my problem with the show always trying to villify Rush. He really does seem to be working towards everyone's best interests and yet the show wants us to think he has a hidden agenda.
The most obvious example was after Destiny flew through the sun, the idea is put forward that Rush might have known all along how this would turn out. And the evidence to back it up? He wanted to be removed from the lottery.
Removing himself from the lottery is perfectly consistent with how the character had been depicted up until then. A depressed loner who has lost hope in life. There was no need to bring this idea to the table, as it feels like a tacked on at the last minute idea to make things seem more interesting.
The "does he have a hidden agenda?" angle of Rush is something I wish they would drop. It adds nothing, Rush is already rude, has questionable morals and any number of personality disorders. These right here are anough to make an interesting character for the audience to watch and a pain in the ass for the other characters.
