First, if someone does something immoral but out of ignorance believes they are doing good, how much responsibility should they bear for their actions?

Secondly, these premies you know, some of them I presume are your friends, so you are their friend, which means they trust you a little, right? So haven't you told them that the allegations on EPO are true? I appreciate this might be difficult, but knowing the truth as you do, do you have some responsibility here? I'm lucky in that the only three premies I was in regular contact with towards the end of my premie days have all since exited, although I have attempted email contact with others.
