Does this magic spell harm someone?

Theres a spell that says i have to stick a needle through the wick of a candle & say "Needle in the flame, needle of fire, pierce his thoughts. Make him writhe, agonize, till his heart turns back to me." I know it sounds like a dumb question, but it was under white magic & i dont want karma to get back at me. So, my question again would be if i did this spell, would it hurt someone? Please no sarcastic or rude comments. Thank you!
