I'm sorry, but Lorna's not responsible for the Genosha genocide. People were going to die regardless if Lorna acted or not. The Sentinels are what caused all of that, and it's not something Polaris is responsible for. Wanda is the person behind M-Day. She was given the power to do that, but not given the specifics to do exactly what she did. I just don't think there is a strong correlation between the two personally.
