Did I Fuck Up My Playthrough?

So I decided it was a good idea for me to make astarion pickpocket gortash after you initially meet him when you get the pass to go to the lower city. Then I passed a check and they let me go to the roof, which led to his main room where his treasure is. After murdering everyone on the roof, which was a hard asf fight btw. I managed to lockpick both chests and steal the helldusk armor and some high vault key. Along with some other goodies. Did I just fuck up my playthrough or is it recoverable?
