User blog comment:The Demon Archer/Dean is a dick to Adam/@comment-26067572-20150411143858

Because Sam and Dean are douchebags (no, i'm not a hater of the series, but that's the truth) Sam and Dean.. well, often it's more Dean than Sam but, they're basically douchebags. Go watch the series again and watch carefully Dean's behavior towards Adam, Castiel and even Kevin or other people.
