well, op is fine with death, so i don't think he's not accepting the consequences of his own actions. he just isn't tuned yet into frontier's specific framework of actions and consequences. you know, that funny place where pad loitering has far worse consequences than executing a peaceful trader. granted, not unlike real life, where you can be punished far more severely for, say, downloading a movie infringing copyright than for hitting someone in the face. you know this peculiar system pretty well, so you have wrapped your mind around it ... and forgotten that you have, so it just makes sense to you.
he doesn't understand the need to teleport him (impressive narrative, btw) 270ly just because, and i don't either. actually, there's no explanation except the devs somehow thought that would be oh-wow-so-cool, and turns out it isn't. i would love it were, but there's no gameplay associated. no specific experience. you can't liberate prisoneers. you can't bribe your way out or escape. not even the setting changes, it's just a commonplace megaship or station and the interface is ... your friendly rebuy screen. what's the point, if not just trolling players, fake content?
arguments? i don't think this is something you can really argue about? gods decide, and it either works or it doesn't. it doesn't for me. the whole crime system is a convoluted mess that completely fails the purpose, which is to provide fun and interesting gameplay around crime.
Err, you can't argue he is accepting the consequences and then immediately explain why you feel he rightfully doesn't accept the consequence of being teleported away. Beyond that (and I dont know if you are willfully ignoring this) this is an outlier situation. Normally prison centers are much closer, but OP intentionally went to a very remote system. You could argue it would be better to place a prison center near that region too. But you can't argue there is 'no reason'. If you're busted in GTA you go to the police station. When you're killed you go to the hospital. When it happens when you are very far from either, you are transported very far. Because it is a simple rule. "Going to spot x when y' is a very common and simple rule in gaming, and 'when you are far from x when y you are moved far' isn't excessively difficult to grasp.
Like it, don't like it, that is just preference. But the 'OMG so convoluted and difficult to understand' is a bit weak, from my perspective. Or I am incredibly intelligent, that is also possible...
