After reading the postings, and a few moments quiet thought, i would vote no.
Just because somebody is an aikidoka for any Length of time doesn't mean they have become a better person.
While someone may be polite and respectful on the mat, doesn't mean they aren't an a**hole in traffic, or have those little struggles and emotions that all humans have ie pettiness, jealousy, selfishness, plain old pigheadedness and so forth.
Does (insert sport of choice) make them a better person?
Like, say tiddly winks, or water ski-ing?
You are what you choose to be.
