That’s not at all how psychological evaluations work - the participant is not asked “do you enjoy killing people?” It looks like about 90% of police officer jobs use psychological evaluations as a screening tool: https://www.thebalancecareers.com/psychological-exams-and-sc...

The effectiveness of such evaluations as screening tools can certainly be questioned, but given that you had no idea they were even used makes me think you probably have little-to-no-knowledge if how psych evals are conducted or how they may or may not be accurate.

And the notion that a psychopath would go through the substantial process of applying to be a police officer, then go through the academy, then go through a probationary period... just to kill another person, instead of just killing that person, is cooky. Obviously we have significant problems with the behaviors of some of the 650,000+ law enforcement officers in the US, but what your describing is not a part of that.
