“If you say you are a Christian, they have to behave like a Christian, or you are a hypocrite”
Not necessarily. A person might just be a bad Christian, or weak, or just falling short.
You’re a hypocrite if you hold others to rules that you don’t even try to follow yourself, or perhaps to rules that you think shouldn’t apply to you.
Human weakness and failure are not at all the same thing as hypocrisy.
There is also cognitive dissonance, or just inconsistency. As for hypocrisy, there is the old saying that it is the tribute that vice pays to virtue. We admire the saints but don’t have the will to imitate them.
