It is not just that people have a evil inclination [yezer hara]. Rather people have a very specific yezer hara--to betray those that do the most good to us and we owe the greatest gratitude. Not just lack of gratitude but even to do positive harm to those that have helped us the most. So while there are all kinds of yezer hara, this one seems to me to be the worst of all
[You can see examples with the hatred of people towards the USA, when according to their enlightened views they might have done better by staying in Somalia. Instead they come to the USA to turn us into another Somalia. [which recently blamed whites for not staying there and teaching them how to run an economy. Or course it is hard to blame the whites for leaving since they were being murdered.]
Another example is fathers who are by default the arch villain in the minds of most people. Again the same reason--to repay good with evil.
I am no prophet, but I can say with some degree of confidence that this can not end well. There is a Judge and justice. People that betray those that have done the most for them will almost certainly not end well.
