A hardcore criminal who has always hurt others agreed would not be able to change overnight, but what many of you guys fail to realize is that even in criminals there are shades, and levels. Yes, Addu is a criminal. But he is from a good family, and we have to understand that he was in a situation where he had to steal, cheat, and lie to be able to survive. He was tortured as a child, and day in and day out he blamed it on Mohan. As a child, being kidnapped, he could not show his weaknesses. His emotions. And therefore he focused all his energy on his anger, which allowed him to survive and get to the level in Dadda's gang. All the meanwhile blaming, and hating Mohan for it. If he really was a criminal, he'd get use to this, but no he blamed becoming a criminal because of Mohan, therefore I don't think he liked doing what he had to do. But it was his survival instincts. I'm not saying that he might have something good planned for Mohan, and that he indeed has changed, because some old habits are hard to die. But to initiate becoming the person that he once use to be, I think is not impossible, even if it was showed overnight.
