I'm writing a comic in which a lot of my characters use 'white magic's. What if they were causing the trouble all along? I would basically force the readers to learn to love characters and then reveal their true evil and make them wonder how they could love something so diabolically bad.
No no no you don't want to do this. Tricking your reader like this isn't good. You don't want to make your reader feel as though they read your story for nothing. This takes away all the stakes and conflict. A trick ending is never the way to go, and is a sign of lazy writing
*I saw you chase a bird down to make it a pet, and I'm the only one that bothered to help with the scratches. *We are both the only people that understand what is happening in this class and keep making snide comments to each other. *I saw you with a dog on campus and ran to pet it. *^The dog is now mine/I demand visitation rights. *I'm hiding under your study desk because I don't want to talk to mu professor that just walked by.
