No. If it moves it moves and even if you turn it the wrong way a bit, it should be easy to get it out if you then turn it the correct way. But there is no standard that is left-tighty on the non-drive side so you can't have got it wrong (unless the frame was built wrong, but that's also impossible because it's a lugged frame).
Water pump pliers are not a good enough lever and will also mar your tool. Use a vice as suggested or a socket wrench (with a tube over the handle to make it a couple of feet long if necessary).
