It could also be that staying in line with what one wants for the future, treating people as they themselves would want to be treated and living up to their own belief systems is just too much work and too difficult.
Why would anyone feel that treating someone right is too difficult...that's plain selfishness. Well humans want onlybwhats best for them but hardly care about others and it's wrong. If we cultivate the habbit of treating people right then it becomes a way of life and very easy to do.
I always try to treat people like I, myself, want to be treated. It is also a golden lesson I’m trying to teach my kids. The term right is difficult to quantify. What is right? That why I do like to reflect it on my own!
