Why does Herobrine like his brothers rather than hate them and make them his enemies?

When Herobrine first saw Notch, he was terrified. Because he's an Aetherian, Notch hugged Herobrine until he calmed down. Herobrine appreciates that.

Steve uprooted a tree. Notch was really confused but Herobrine stood there shocked, then began to laugh and said "I like him".

Also guys I am leaving for summer camp today. Friday I come home, but I leave for Missouri the following day so I don't know when I will be online for the next week or so. The connection is always spotty at camp and I don't know what it'll be like in Missouri. Love you all! <3
