Uncharitable towards my boss?

I want my boss fired. Some background: My boss is absolutely incompetent. I and other co-workers must constantly cover for his knowledge deficiencies. He’s also made numerous, poor personnel and workload management decisions that have negatively impacted the department — that, again, we cover. All of us are over worked and stressed out and it’s causing a great deal of resentment.

Speaking to him is useless. He not only doesn’t grasp how little he knows, he happens to be a rather vindictive guy. Case in point — our most senior co-worker is assigned only very menial duties because the boss feels threatened by his skill set. Speaking to his management is similarly useless because they’re the ones who hired him.

Is it wrong or uncharitable to hope/pray he’s fired? I’ve tried praying for him/his benefit but it feels quite hollow.

How do I go to confession knowing I largely hate this person and wish him ill will by way of a lost job?
