no, no, no, and no.
...Mental illnesses that cause murder are not any more controllable than one's sexuality. Do you think a homosexual can choose to be straight? No, not unless there is a chemical change that takes place in the brain. Same goes for many other variations and irregular behaviors of the human mind.
What we *can't* do, is be
mad at these people. That's pure stupidity at the highest level. They're only acting according to their chemistry, and why should we hate someone for acting according to their chemistry? They can't help it. Would you hate a bear the same way if it mauled your grandmother as you would a Catholic priest who raped and killed your grandmother? would you hate a car that malfunctioned and drove your grandmother off a cliff? Would you stab or shoot that car with a gun because you hate it so much? Would you send the car to jail?
Please start watching at the 4:00 mark when you get time. It's important.
