A witness should be in control of himself and be able to make important decisions himself. He should be able to work with a clear mind also when there is much noise around him. He should care about what is being discussed regarding the future of Steem and should always stay true to himself, not just blindly follow the herd into the darkness.

I won't vote for witnesses that are at any point willing to freeze other accounts and I prefer to vote for people who focus on Steem's success instead of drama.
