Is he just venting in privacy of his home to his wife or he blurts stuff like that everywhere? Does he wish harm on these people?

Both I and my husband have very stressful jobs in somewhat similar fields. It’s a different career path but dealing with the same population.

Neither I nor he would ever harm a fly and we would go to great length including endangering ourselves in order to save and protect those who put their trust in us.

But when we vent to each other in privacy of our home after particularly hard days we sometimes have to let the steam out and might not always use the most refined language. I’ll give you an example. If someone we take care of (patient or child etc) is being mistreated by drunk relatives I surely would refer to them as “crazy freaking drunks” and likely worse than that rather than calling them “these people addicted to alcohol are not being nice”.

People who don’t hold dangerous or high pressure jobs sometimes don’t understand that we have to let steam out if we want to make it. I am not saying it’s all right to use bad language or put others down, but I am offering a new perspective/a different look at this.
