We do not have to be purposeful in harming others to do harm to others. All we must possess is a lack of compassion, empathy, and relational-boundaries. Even when I feel I am at my best I can do my worst. Compassion, empathy and relational-boundaries govern the actions of love. If I lack these commitments, I allow my love to become disordered and dis-regulated, and not resemble love at all.

“This is how we know love: Jesus laid down his life for us, and we ought to lay down our lives for our brothers and sisters. But if someone has material possessions and sees a brother or sister in need but refuses to help—how can the love of God dwell in a person like that? Little children, let’s not love with words or speech but with action and truth.”
1 John 3:16-18

“Don’t be in debt to anyone, except for the obligation to love each other. Whoever loves another person has fulfilled the Law. The commandments, Don’t commit adultery, don’t murder, don’t steal, don’t desire what others have, and any other commandments, are all summed up in one word: You must love your neighbor as yourself. Love doesn’t do anything wrong to a neighbor; therefore, love is what fulfills the Law.” Romans 13:8-10
