Best (non karma) ending for Those! ?

Like the title says, regardless of karma, what's the best moral ending for this quest? On one hand, Lesko does have a good goal that would help a lot of people. On the other hand, he doesn't care about anyone dying and sees it as acceptable casualties. I'm torn. What I did was I killed the queen, then killed Lesko. But I'm not sure if that was right. I'm curious to see what other people think.
