Comments of chapter undefined of Demon's Virtue

There is absolutely no reason Eiro couldn't have just finished this fight immediately. The longer this fight goes the more people die and the more risk he puts his loved ones in. If it weren't for Rudy's unique skill he would have already been dead, it could have also been any of his other kids taking a walk outside too. He's already aware that his overconfidence nearly got his family killed. So what is the next thing he does? Immediately becomes super cocky and overconfident creating some over complicated scheme using Rudy instead of just killing the enemy as he clearly could have.
