Yeah she's a merc and would do things like that for money, it's that in Weapon X-Force she's money mad, to the point of wanting to rob a bank for money, Domino always had more brains and class than that...and if she got offered a HUGE amount of money she'd be VERY skeptical of whoever it was that was offering the money and what and why they came to her with the job and would wonder if the job was the right thing to do, that sometimes it didn't matter how much money they offered, she had standards...
