Is it wrong to always feel right?

Nothing is wrong because this is indeed human nature, this is not a matter of right or wrong, it is the fact that every human being does need his own truth. Humans must hold to a principle they regard as truth and fight what they perceive as evil. But the way to defend the truth is not to force others to accept our point of view because, as explained before, if people are convinced of the truth, then they will not be able to accept something that they think is not true of fact and logic.
