killua and gon

I have checked HxH recently and it became top 1 anime for me. pemain drama bad and crazy But i don't really get the actual relationship between Gon and Killua because chimera ant arc did a lot to change the main characters. pemain drama bad and crazy And there are many videos, comments where people express their view on Gon and Killua and it sometimes comes to "Gon is monster! He betrayed Killua!!"
