I agree with this quote 100% Also excuses to justify your actions also doesn't make you look cool. It makes you come off as the person who takes no responsibility for your actions. Belittling someone and making excuses eg they 'deserved it' will not slide.
Stop being a dick. be nice. It's not that hard. I'm sorry having respect and compassion doesn't tickle your peach.
