You are focusing on the wrong part of Zane's life. He had a previous life where there may or may not have been a Padme character. (I sure hope there was.) He then went evil/crazy and started destroying everything. I good friend had to kill him, but his dying body was sent to a good Palpetine, namely Julien. Julien got rid of the old memories but kept the personality of old Zane except for small things like his humor switch. When Julien knew he was going to die, he knew he had raised Zane right and that he would not turn to the Dark Side. He used the memory switch to save Zane from the sadness. He kept those memories because he thought he might meet up one day with Zane again.

So basically the turn to the dark side happened during Zane's first reset and Julien made sure it couldn't happen on the second.
