Good and evil are christian terms which I avoid.
I am also very much a librarian, but I dont think it would be a good idea to make guns accessible in europe as in amerca. There you can get executed for misuse, but here you can get like 21 years and if youre a moslem 'cultural - enricher' punk, which I suspect the most energetic users of these weapos would be, then you'll probably get an easier sentence. "I mean of course, these people have fled from wars and are brought up in very bad conditions, oh no, not because theyre culture is bad, oh no it's wonderful and respectful to women, of course, but because we dont give them enough relief and economical security etc. In fact, maybe we should give them guns in order to protect themselves against 'yhe increasing threat of right extremism', (which can hurt both you and me - these people are absolutely crazy) and maybe to punish us europeans, oh yes theyre european too, but the other us, for being so cruel to everyone.
