The woman, by her own choosing to participate in these negative or destructive thosenes (of cruelty to cats), is heavily intruded upon at a consciential level, and is thus unable to perceive or understand the cosmoethics (or lack thereof) of the situation clearly.
Notwithstanding, as in all cases of intrusion, the karma of her involvement is still hers (just as the intruding karma of the intruders are their own), as at all times, she is still responsible for her free will; while the process of intrusion indirectly supports the carrying out of the difficult karma (and by karmic inertia, exacerbates the difficulty and makes it denser to break through the illusion), the end result must come from her free will. In doing so, the balancing of the karma (which will see her meeting the consequences of her actions back to her) enables an evolution for the aspects she is dealing with, involving these issues.
