Generally no, probably because many males when they end up in physicality make it some kind of dominance thing (playfully violence that's just a little too much, "higher position" touches like hand on top of shoulder or physically leading other people and even the good old "measuring somebody one the firmeness of their handshake"). It's not casual and friendly when there's measuring and testing of others involved.
Outside close family, the only environment I've been in were things like hugs were normal was the Theatre world.
The difference between a sociopath and a murdering sociopath is the belief that they will lose nothing and even stand to gain from murder.
Absolutelly, evil people are to blame from doing evil shit because they chose to do it.
Other people who protect and support the evil people when they do the evil shit are also to blame because without their support and protection the evil people are a lot less likely to do the evil shit fearing the repercussions.
In this specific instance, given that the US has been vetoing UN Security Council resolutions to stop Israel and is by far much more powerful than Israel in the World stage, the theory that they're the "main obstacle to peace in Palestine" makes sense, or in other words, that the murdering sociopath would have to stop murdering due to fear of the consequences if the US stopped supporting it.
Whilst it seems likely that it is, whether the US really is the "main obstable" or not is something that we would only know for sure after the US stopped supporting Israel.
