How would she feel if the same thing happend to her?
She doesn't think she will have any problems, for the house is in her name. She may be the only person in the USA who can control that monster FOR NOW! She probably admires his strong "masculine" presence -- powerful man killing an innocent victim! Some are too blind to see.
Actually, I think she wants Terri dead as well so she can marry her man!! She wants Terri dead cause what would happen if Terri got better, her sweetheart Michael might go back to his wife, and she can't have that. no, she wants her gone just as bad as Michael, but for her own selfish reasons! She is insecure!
