is that a bad thing?
no, some people might think so
a person who does wrong and denies it has done wrong twice, while someone who does wrong and admits it (with guilt, not pride) is a better person for doing so.
if you own it like "YEAH I SPAMMED THAT SERVER HARD I'M COOL FOR IT TROLOLO HAHA NOOBS" then you're an idiot
defending yourself is sadly often not taken well here
