Seniors?? is it legal to take a life insurance policy out on another person?

My mother bought life insurance for me and I didn't authorize her to do so. We don't have a good relationship at all, and I don't want her receiving any monetary benefit if I ped. I already have life insurance through my partners job so I didn't need her to buy other life insurance for me. I recently went to her home and took out of her possession the life insurance policy and I plan today to call and cancel it. How dare this piece of crap mother of mine be allowed to scheme up some mess like this without my authorization. I need advice please! Thanks seniors! Oh im sorry about coming into your territory with such a shocking avatar picture lol.
