Would it change your perception about a person to former drug addict?

As much as i like to say that nobody's perfect and everybody deserves a second chance. And as likely it is that mayber it really isn't there fault but instead was the environment that this person grew up in i can't safely safe that i wouldn't see this person differently. No matter what this person's past would influence my assumptions about this person.

no at all. What matters is now. I really find it interesting asking him about what he went through just to get by. and i assure, it has been really hard for this people. you should also appreciate them for winning over these challenges.
