Ok so i played infamous through in evil.  When i got to the second to last mission where you choose to either destroy or use the ray sphere again, i decided to use it and doubled my powers.  Now i did sum research and found out if your a hero and activate it, you turn infamous automatically.  So what happens to me?? if i decided to destroy it?  Do i turn into a hero?

Maybe?

That's right, you turn into the Hero if you destroy it. It's a nice cheat for Trophies. Save your game just before the mission and either destroy or activate the ray sphere, then save it on a different save slot.
Now you can easily finish the game on good and evil by doing just the last mission and getting both trophies.

Didnt know that. But i guess it makes sense.

Need to play this game again. Hero story is amazing.

This. Althought I didn't do it, I wanted to play through twice .

And just for the record, I prefer the  hero story. Also the hero ranks have my favourite upgrades [the one for megawatt hammer] and inFamous my second [Arc Lightning].

wow really??? u sure? so if i had infamous rank and decided to just destroy the ray sphere instead of activating it... i become instant hero? gotta try that...

yes indeed, I tried and tested it and it worked for me, it's pretty cool.

ok one last question, after u beat sasha in the boss battle, u get to see a cutscene where cole distinctively says that Sasha before the blast was already bad and now she has gotten worse.  WHen i heard that, i thought i mustve missed some dialogue that told how cole knew sasha before the blast but nope... so how does cole know sasha before the blast?  wasnt she just part of the reapers? a normal person with no powers?
