the Power of Feelings has been for the entire series has been something positive, and not negative, if you are looking for people doing bad things with the power feelings look at Curses, their power stems from the power of negative emotions.

This is not real life, this is a magical world where anything can happen, villains who try to use their magic to satisfy their own selfish desires will ultimately fail.

I am not talking about reality you are, but if you want to talk about reality go ahead because that is wasted on a manga but here is something that is as much realistic as any humanitarian thinks, Those fanatics are not choosing their path of belief, they are choosing death, rather then living for the sake of their comrades and their belief they are abandoning them in vain, nothing good could ever come from it only more hatred which will never end until there is nothing left, the only way it can stop is to find peace and forgiveness. Many of those fanatics were probably not raised right and we're looking for a higher purpose or fame or just want to f*** things up because they are f***ed up that way.

And those righteous villains in the manga who say they belief what their doing is right are just lying to themselves, Meredy's magic betrays her in her fight with Juvia for her feelings poured right into Meredy, then there are those who abuse magic such as Angel's Celestial Spirits against Lucy, they don't want to kill Licy because Lucy loves them. Laxus could not kill all of Fairy Tail with Fairy Law because the magic saw the truth in his heart, Karin Lilica enjoyed torturing her spirits and feels like they are merely tools but they are not, they are alive and have feelings of their own. Magic is not just some power they can manipulate to satisfy their own desires however they please, magic is alive, it thrives just as nature and every living creature grows and is nurtured by love. Love is really the basic factor of life, just as life is the basic factor of magic.

Also, I am not arguing anything, I am confirming that Power of Feelings is an actual power and not some plot device, which explains everything now.
