If I leave $20 on the sidewalk the thief is wrong for stealing it, but it is partially my fault for being stupid enough to leave $20 on the ground.
This can easily happen to anyone -
5PM Friday - $admin and $ceo have a fight
6PM Friday - $admin decides he's had enough with $company and $ceo, and wipes everything
7PM Friday - $admin is fired
Where are your exit procedures now? Are the current admins stupid for not having the foresight that $admin and $ceo's fight would have resulted in the worst?
