@Ionus,
I can't compare my life experiences with yours, Ionus, because my life has been very different to yours. I'm sorry there has been so much difficulty for you & for people you have known.
But (from my experience of life) I really cannot agree that 90% of people are capable of being so evil.
That is not to say, of course, that one should blindly trust everyone & expect the best of people always.
It's just that I believe that it's worth giving people a chance. To not trust
anyone because they
may hurt or betray you seems to me to be a very self-limiting way to live one's life.
