A little too harsh to say you want someone's entire family to be turned into red mist because of stupid actions of one guy.
Regardless, I think they just get satisfaction from finding vulnerabilities in sites and exploiting them. I can only assume they look at the sites they hacked as trophies of some sort.
it's like if a cocasian hacked your site to promote his personal agenda, would u bash his entire community based on that one person's believes?
