I feel that I have betrayed my people. I didn't join the Caldari Navy and I am now fighting as part of a player alliance that does nothing for the Caldari State.
But the worst thing I have done, is that I have used technologies that was developed by the enemy, the Gallente Federation.
I have used ships like the Megathron, Ishtar, Myrmidon and the Brutix. The isk I paid for these ships have probably been used in one of the enemy's research projects.
Remember that when you use ships that wasn't developed by the State.
