Hate can be a good thing

"The man who lived in this constant fellowship with God manifested in his daily life all the fruits of the spirit ... and with them was a hatred of their opposites – a loathing of every form of sin"
'Spurgeon: A New Biography' by Arnold Dallimore

Hate is something I definitely don't have enough of. Do I really hate the sin in my life, or do I half enjoy it? Do I accommodate it because it's easy to? And when I sin, do I go all inward-looking and self-defeatist?
Surely we should stir up an intense hatred of Satan.

I think you could argue that all sin is essentially demonic in nature, because to sin is to rebel against God. And that's what the demons did. Giving in to temptation is to go against the very being that sustains the universe and gives you life. Hatred of sin and Satan could well be another weapon in your pursuit of holiness.
