But Hermione unfortunately didn't think like that. While she understood that nearly every spell can be seen as black or white, she still struggled with that concept as a whole. She knew it, but didn't feel it. A sewing curse, normally used for materials, can be used to sew the windpipe closed for an example, an Avada could be used to put animals down pain free. A boiling curse used for cooking, could boil someone's blood and an Imperius used to control, could also be used to save someone's life. If that person would try to kill themselves, a well placed imperius could bring them back from that thought.
