It's all part of Betheda's goal to appeal to a broader audience.
While a lot of the more experienced fans would know better than to run around killing everyone in sight like a GTA game - or accept the consequences for doing so - a lot of gamers would do it and then whine about all the quests that are unavailable to them.
It's a lot like essential quest related items. Bethesda have to cater to the idiots who would whine that they've failed a quest because they lost a certain item.
Prrreetttttyyyy much.Yes it's a shame that so many NPC's are unkillable, but it is what it is, they made the game to appeal to both hard core RPGers and newbies and in order to get and keep the newbies some changes had to be made.Wasn't the list of unkillables about the same size in Oblivion?Any way the game has been geared to pick up new players and to try and keep the old players, this is life get over it, there are bigger issues that the Dev. team have been preoccipied with.
Why would you run into the marketplace where everyone can see you and the guy screaming theif - that's stupid.
The game isn't based on anything remotely modern in RL, but as for back in the medevil times, yes, you probably would have killed the merchant if he caught you
No you would not have killed the witness, you would have ran for your life. Laws back in medievil times were enforced with an iron fist, not the hand holding of today.You would have lost your hands for theft, and death was handed out on a routine baseis for even (what we see as minor) minor offenses.Or you would end up locked up in the towns tower for god knows how long, you would have been tortured etc....The only way this argument makes sense is if your travelling the road and even thenafter so many killed witnesses your name would start to spread as a blood thirsty killer and then you would be hunted down like a dog.
Face facts, your argueing a topic that will never be addressed, and I agree with an earlier post, that you should play some GTA if you want to go on a killing spree, other wise do some research into the judicial system and punisment of the medievil times and rethink weather or not you would kill a person with in a town.
