People need to look at their teachers for what they are and no more. Don't assume that just because the person has mastered a certain degree of technical proficiency, this has much bearing at all on his proficiency at being a human being. Don't assume that just because the teacher is a fantastic human being, their Aikido is very good. Technical expertise does not in any way equate to wisdom nor does wisdom necessarily infer technical expertise. Only occasionally do we find a teacher who has both.
