What was the underlying reason for John Ipe’s disgust with the world?

John Ipe was disgust with the world because he was not getting fame and name which he wished to be. Being an entomologist he found a species of moth but it was not given his name and this made him disgusting with the world. He was already a hot-headed person who could not see anyone else to do something better and get attention but her wife was getting that which made him feel disgusting. This jealously, in turn, made him beat his wife Mammachi, just to overcome his frustration.
