We very much respect the two forms that are opposite to it: love and hate. Pharaoh, Haman, and all the other sinners described in the Torah are very important characters. Without them, we would not be able to rise to holiness. We receive all of our vessels, desires, from them. All of the righteous men stand opposite them because the Creator made one against the other.
Therefore, it doesn’t matter whether a person supports something or protests against it. The most important thing is that he cares about it very much, as opposed to being indifferent to it, feeling that it is “neither here nor there.”
It is possible to awaken a spark in anyone. This spark is concealed in every person because he originates from the broken vessel. Therefore, he definitely has a spiritual spark and it can be awakened. The only question is: How deeply is it concealed?
However, when this spark is awakened, he might react negatively: A person does not want to hear about it and he curses himself, the Creator, Kabbalah, and the whole path to bestowal. He does not agree to it and hates all of it. But Baal HaSulam says that this does not matter. It’s the same as if he agrees to it, the same as if he wants it because he is revealing his desire in this form. Even if the desire is corrupted, he already has it.
