The only exception would be Lillian Voss, who thought she was still a normal human and when showed her own image, she refused to believe she became a forsaken until she tried to return to her father, which was a Fanatic of the Scarlet Crusade (who wish to exterminate all undeads and non-members of the Scarlet Crusade.) After she was faced with the hard truth, she embraced what she became and went on a killing spree in the camp where she lived.
Gilneans however hate what they became and are trying to search for a permanent solution (undoing the curse). I mean, if it wasn't for their arrogance, egotistical behavior, sense of pride of their city and culture and knowing that if they die that they would become forsaken and forced to destroy their own city, most of them would have committed suicide once they regained their humanity.
Take Godfrey, he threw himself of a cliff in order to avoid becoming a worgen. He got reanimated by Sylvanas and eventually killed her because of his Gilnean attitude and because he wanted to control the kingdom himself.
Gilneans feel like they're better than anyone or anything else, them being reduced to being savage beastmen is something that hurts their pride, they hate every fiber of their being, whilst Forsaken (undeads belonging to the faction of the forsaken. Godfrey himself isn't a Forsaken.) embrace what they became.
And yes, the Forsaken are evil. Gilneas was an isolated kingdom that refused to work with the Alliance until the Forsaken attacked them. Gilneas didn't mean anything to the Horde, they weren't their enemy, neither their ally. Garrosh just saw it being convenient to support the attack on Gilneas because it would mean a new port for the Horde (and because he is forced to do so, otherwise he would lose the Forsaken as his allies). If the Forsaken didn't attack in the first place, then Garrosh would have minimal interest in Gilneas.
