I'm not sure that anything is going to change anybody's mind on this thread, but my sense is that a lot of feeling comfortable is based on familiarity. The longer you spend somewhere without anything happening to you then the more relaxed and at home you feel. Those people on this thread who are speaking up for Peckham seem to be the ones who have spent a lot of time there, have had reasonable experiences and tend to appreciate the many things it has to offer. Anecdotal experience can only offer so much (and I have a horrible unease about tempting fate) but I have worked in Peckham for almost six years. For the first three years I was based in Camberwell and walked through North Peckham daily (to get to different schools in the area). Currently I work in the centre of Peckham. I also use the station a lot, sometimes coming back in the evening. My 20-something niece lived with us for a few months and often used to come home very late via Peckham Rye station. For what it's worth, it has always been fine. I think it helps too that through work, I know a lot of children and young people who live in Peckham and generally, I like them a lot.
