You are wrong! Hacker is hacker. When there was no laws and unnecesary prejudice against people who understand computers and hack into computer networks, all hackers were called hackers. Crackers are neologism artifically created to distant from people who hack websites, write malware and other stuff. This is wrong. I have seen on numerous ocassions how so called "white hat" hackers from well known security companies get boored and deface websites just for fun.
Basically in my opinion it is not evil to deface some website, take down some small part of network or write new piece of worm as long as the CRT monitor of the victim does not explode and blast shrapnel in face.
So you are fine with burning down a mom and pop store as long as you don't kill them in the process? :rolleyes Ah, naivete.
