I have no doubt that Adalind would've went along with Kelly if that's the price she had to pay for being with Diana. Remember that Kelly also provides protection for the two of them and that makes it more of a certainty.
This is the same Adalind who went crawling back to Viktor and did whatever he told her to do in order to be reunited with Diana and she was just running for her life from him. Adalind's character isn't why Kelly took Diana from her because she already acknowledged Adalind would die for her daughter despite the history she shared with Nick.
