Very strange. He was a common man like any other. He may be better than many of us and May Allah forgive him as we all commit mistakes and sins at some level. But, saying this that this gap will never be filled then I would say it better not fill up.
We need leader and scholar who lead us on the foot steps of our beloved Prophet (PBUH). He is known for his forgiveness kindness, humbleness, soft spoken-ness even with enemies. We don't want somebody sits on member and swear at everybody even it is because of Prophet's love because I am very sure my Holy Prophet (PBUH) will never like it.
We worship deads and swear at livings. Even worst person die we will say what a good person he was and we will find good aspect of his character even there is none. But if the saint is alive, we will try to find bad aspect of his character if there is none.
May Allah give us hadayat. Ameen
