This is a very complex question, and Im glad you asked it. As the Catalyst (pun intended) for several rage quits, I can say for absolute certainty that I have no clue, but im sure with a little deductive reasoning, we can figure it out!

First, the brain goes through a process of grief. Those stages are:
1) shock and denial, an attempt to avoid pain by denying the loss;
2) pain and guilt, a period of devastating pain and feelings that life is chaotic;
3) anger and bargaining, including emotional outbursts that can permanently damage relationships and attempts to bargain with a higher power for relief from the emotional pain;
4) depression and loneliness, or a period of reflection during which the person realizes the full impact of the loss;
5) upward turn, when the person begins to adjust to the loss;
6) reconstruction of life without the loved one; and
7) acceptance and hope. Acceptance does not imply happiness. Instead, the grieving person can now reminisce about the loved one with sadness, but without intense emotional pain.

First, the victim..cough...person is shocked to find their ship is destroyed! That didn't just happen! NOT IN HIGHSEC!!!!
Then, they experience copious amounts of posterior pain and or rump rage over the loss of their vessel.
Then, they usually go on a long extended tirade in local. They even demand that you repay them for their loss!
Then, they get all mopey. Their ship is gone and they have no monies to replace it! ::sadface:: Theyre all alone in their one man corp..and being an anti-social highseccer..they probably have little to no friends.
Then, They realize that they can petition you! You ganked them in Safesec! That HAS to be against the ToS/EULA!
Then, they realize that what you did isn't against the rules, so they dock up and grab a noobship..or wake up in a fresh clone. They now get to update that clone and purchase new implants!
Then, They accept that Eve is not for them, and in a hopeful rage filled QQ thread, they hope that a GM will see it and take action. They talk about all the fun they had in Eve, but ultimately go back to WoW.

I hope that help you with your question.
