Do you think that, if silicone sex dolls and robots were cheaper and easier to have access to, it'll reduce the risk of rape, paedophilia and some other sex crimes.

Why I think so is that, they are sold in japan, yet the rape rate over their is better than before. Just like their pornography, it's seem worse than the american ones, some includes force sex scenes and sex with apparently under-aged girls but their sex offence rate isn't as worse as that of some other countries that don't allow these things, e.g US or UK
NOTE:This was the category that was recommended for me to ask this question at, what's so offensive about asking a question like this, I didn't use any dirty words, did I?
Well, killing thme might sound right, because at the end of live it's the kids and the raped women that'll regret such experience, but the question is how can we prevent such things from happening, because any body can be a paedophilie but pretend not to and not tell anyone or show it (who would have the guts or the balls to say he is a potential rapist or sexually attracted to children?!, coz he knows telling the people can cost him his reputation or his life).
So like they say 'prevention is better than core'; that's why I think this is a way of preventing it
sorry, for my mistake; core=cure
