The problem with people is that they're only human.
I'm not interested in perfection. The universe is perfect, and there are some works of art that we see as perfect, but human beings aren't perfect.
Don't buy into the notion that mistakes can somehow be avoided. They can't be.
We are imperfect beings in a very imperfect world, and the one thing we can count on is that things will go wrong, and that each and every one of us will have problems.
Every man got a right to his own mistakes. Ain't no man that ain't made any.
Never attribute to malice or other deliberate decision what can be explained by human frailty, imperfection, or ignorance.
Only human, after all.
People are people. We'll always find a way to mess up, doesn't matter who's in charge.
