Yes, SHE probably wanted to kill hundreds of people at several locations, but didn’t plan on real police officers who were willing to do their job and take her down quickly.
I have no idea what the “total destruction” she envisioned could possibly mean. Did she create some demonic plan that copycats might attempt to accomplish?
I wonder if Hale might have entertained other notions / ways to kill large numbers of people besides with guns? Ugh.
