Now, let's discuss the reason why Saitama took them in. Is it really just because they are freaks? It was originally just a little pet of a strange snake king with genetic variation. After the beast, it lost its owner and weakened into a normal-sized dog. Later, I happened to meet Mr. Saitama in the ruins. After making sure that Mr. Saitama meant no harm to them, he joined Mr. Saitama with the black spirit, who seemed to be very useful to Mr. Saitama. Genos in the Front, Snow Blowing in Hell and Shining Body all interact with Saitama in these ways. Looking back, Saitama's response to him was obviously different and unfriendly, which led to this situation entirely because of the personal behavior of Heijing.
There is no doubt that Saitama didn't take in the black spirit. In addition, he also confirmed that he told the black spirit not to come, but the black spirit had the cheek to follow him and took great pains along the way. Therefore, his behavior angered Saitama, but Saitama didn't stop him. It is not difficult to see that the dark elves will be shameless to the extreme. Their stubborn personal behavior left Saitama helpless. The black goblin saw the opportunity, took the opportunity to paste it up like dog skin cream, and slowly wore off Saitama's defense. Finally, Saitama gave in and let Poky and the black goblin live in the dog house outside. All the weirdos killed by Saitama did evil, but those who were not killed, such as the beast, the Baiqi, the black spirit and the grass chicken (the grass chicken didn't die in the third revision), didn't do evil.
There are also bad people among people, such as Sikes with big eyes and "adults" in Endurance Village. There are also good people, zombie men and sweetheart masks among the same weirdos. Teacher Saitama must be a strange level. He is not only a super strong man, a walking geek food expert, but also a small pet collector. He not only collects and sorts out humanoid pets, such as Genos, Blowing Snow and King, but also collects and sorts out dragon-level weirdos, such as Qi Bo and Black Genie, from the Weirdo Research Association! Saitama doesn't deliberately distinguish between people and weirdos like other heroes. It's not easy to stay pure, because they are freaks and must be solved! He doesn't have any resentment against weirdos! He won't kill some weirdos professionally because of some honors!
