It sounded from Silver's viewpoint that Giovanni left him for dead in the games and the manga, not to get stronger. The GSC games and their remakes are the darkest games of the whole series with Silver along with the decapitation of Slowpoke tails.
NIntendo say hi. Giovanni would never leave his son to die(not on a kids game), he left him with the intentions to become stronger, and feed his anger. So your the dumbass. Go screw off. I really LOL'd at your post to try and tell me off.
