Yeah. Unfortunately, you never really know who will turn on you, or when. In that sense, it's pretty easy to be paranoid and distrusting of everyone. But that sort of existence doesn't seem worth it to me, so I allow myself to open up to others despite this uncertainty. The friendships I've been able to forge because of this make me feel that it's been worth it.
I wouldn't say it leads to paranoia. It can lead to general apathy towards people. There was a time when I believed in the things you say but that is no longer something I have faith in anymore.
That's fair enough. I do know a few people who I would say are a bit paranoid in regards to trusting others, but obviously it's not always the case. I haven't had the same experiences as you, so naturally my mindset would differ from yours. I can certainly understand that apathy, although I do not hold such a mindset myself.
And, Kyon, this is probably not the right time or place to say that.
