I'm going to indirectly cause a co-worker to have seizure.
Why do you want them to have a seizure?
He is a real jerk at work and I don't like him.
No matter your attitude towards your co-worker, it is never okay to purposefully cause harm to someone else. Creating a situation where a co-worker could have a seizure could kill him.
He is vile. How else am I supposed to make him pay for that.
You can talk to him and let him know how you feel. You can seriously hurt someone with what you are doing.
