8. A bad and haunting past

If you are guided by emotions when fighting against someone, you’re definitely going to make some mistakes. Well, the same can be told about Spiderman. Haunted by the death of his uncle, due to his own inaction, this is definitely going to play the mind of the superhero whenever a villain brings it up. This will definitely be against a lack of better judgment of the superhero, and at the end of the day, enough taunting can bring about the downfall of this hero. So, all the villain has to do is to keep bringing up the subject of his uncle, and a lot of mental distraction is going to cause enormous problems in the fighting skills of Spiderman.
