Why doesn't our society show more mercy and forgiveness toward doctors instead of suing them?

I think doctors do some of the most honorable, admirable, and altruistic work in the world. They dedicate their lives to helping and saving others from injury. And how does our society repay them? By suing them for just for making mistakes and being human! Almost every doctor in this country gets sued multiple times in the course of their career. That's partly why I support medical malpractice reform 110%! It's the very least we can do to show doctors the respect, gratitude, and mercy they deserve. Whenever we sue a doctor for making a mistake, how do we know the doctor didn't have good intentions and wasn't trying their very best? We should be grateful that the doctors even ATTEMPTED to help us in the first place, even if the attempt was unsuccessful. To waste time and money blaming doctors for something they probably DIDN'T EVEN INTEND to do is FUTILE. It doesn't change the situation and it doesn't help doctors learn from their mistakes. The absurd amount of money that's getting earned from medical malpractice suits is an abundantly clear manifestation of how unforgiving, unmerciful, and immature our society has become and it's about time something was done about this!
