Right, for the sake of completeness and making sure everyone has the facts: here's why I did what I did:
If history tought me one thing, it's not to trust others too much in hardcore galaxies. For this reason I had an infil going on my fam members and earlier today I noticed a player decided to build 98 droids. Now, I found this rather odd, especially within the first 20 hours of a round... This got me somewhat worried and I decided to check with a mod about the current attacking possibilities. It was confirmed to me that attacking was, in fact, possible. I quickly added both facts up and came to the conclusion I'd pretty soon get screwed over. Now, as it happens, my SoR planning was shit, so I decided to use some of the resources I had left for transports. I figured you never know what they come in handy for, despite aid being disabled, planets can still be built up etc with constr science if you work together.
Due to having these transports I decided to hit first. Again, I wasn't gonna assume someone builds 98 droids for defensive purposes and doesn't mention anything about it, even when being asked in a subtle manner.
The only dilemma I was faced with were the 2 other family members. I could let them live and risk a)them actually being in on it so I'd still get screwed. b)them not being in on it, but then they would, despite my reasoning, not trust me anyway. And if I was in their spot, I'd kill me too, just to make sure. It's all about surviving in the end.
I decided not to take any chances and therefor I hit them as well.
It turns out that I was wrong for hitting them, but I was faced with a situation and did what I felt was in my best interest. I did apologise for this in the meantime to the other 2 and I'm trying to fix what was broken, however chances of succes will be slim at best.
In the end I still got screwed, probably to the joy of some, since I got marked rogue. The fact that it was needed for my survivial makes this a bit synical.
Anyway, I felt my version of the facts should be mentioned.
