I was going through Arnika, after starting again (this time round my party seems heaps more efficient and powerful

)
I did the jail area, and ended up behind that massive bank door that has the eight or so tumblers to pick. I thought there would be huge loot to grab behind it, so I picked the door. But to my disgust, it just lead back to the bank reception area. Bah i thought, and just took the teleport to outside, because I didnt have all the ID's to loot the rest of the bank.
Later on after many saves and fights, the bank was the last bit to do, and I went inside. But then the nerdy girl behind the desk went hostile and called the bank guards, so I had to kill them all. It looked like they didnt like me opening their big door.
Is this bank incident gonna affect anything later on? I want to be a "good" guy in the game. It will be a major pain to reload before I picked the door thou
