What i did was wrong?

I was fighting with my friend, so i punched him in his balls and took a vase and smash it on his head, then while he was lying on the floor i started kicking his head, now i have to pay for his hospital fees, but lets get to the point, after the fight, i did something really bad, i am embarrassed to say this but, i felt like i needed to take a leak, so i went to the bathroom and peed on the urinal and realize that all my pee was on the floor, i think i did something wrong because the poor janitor has to clean it up now!
