Depends on who you are talking about when you say the "the devil".

In pop culture, the devil is essentially an aspect of everything bad in the world. everything from cussing to genocide is considered work of the devil. this devil is obviously an asshole and resisting him is a no brainer.

If we were talking about Satan in the book of job, the Tester of Faith interpretation seems accurate. whether he tests faith because he tries to lead people astray, or he tests faith because he is working for God, seems to be up for interpretation. In either case, resistance comes down to your religious affiliation. if you are a follower of God, you would resist Satan. If you are not, then whether or not you resist Satan seems to not matter.

If we're talking about Paradise Lost's Lucifer, he's just a jealous beta male. his reasons for rebelling aren't 100% clear, but he seems intent on co-opting God rather than building his own kingdom. he does posit the question of whether it's better to serve in heaven or rule in hell, but his actions are destructive to God's design, rather than constructive to his own. He's a loser, not really worth thinking about.
