"Such is the power of love in gentle mind,/That it can alter all the course of kind." Which of these best restates these closing lines from Spencer's Sonnet 30?

These lines show that love can blind many, including the kind, and get them to do things that they normally wouldn't do. This is because even if you are the most generous person in the world, once you love someone or love someone deeply, you can get blinded by that love where you are capable of committing the acts of the worst atrocity.
