Was Muhammad a psychopath?
It would explain a lot.
Let's see what non Muslim Scholars in the West, who studied his life had to say to answer this question:
Michael Hart, in the 100: A
Ranking of the Most Influential
Persons in History, 1978.
MUHAMMAD (PBUH), Number. ONE
From the 100, a Ranking of the
Most Influential Persons in
History, by Michael H. Hart
My choice of Muhammad to lead the list of the world's most
influential persons may surprise some readers and may be
questioned by others, but he was the only man in history who
was supremely successful on both the religious and secular
levels.
Of humble origins, Muhammad founded and promulgated one
of the world's great religions, and became an immensely
effective political leader. Today, thirteen centuries after his
death, his influence is still powerful and pervasive.
The majority of the persons in this book had the advantage of
being born and raised in centers of civilization, highly
cultured or politically pivotal nations. Muhammad, however,
was born in the year 570, in the city of Mecca, in southern
Arabia, at that time a backward area of the world, far from the
centers of trade, art, and learning. Orphaned at age six, he was
reared in modest surroundings. Islamic radition tells us that he
was illiterate. His economic position improved when, at age
twenty-five, he married a wealthy widow. Nevertheless, as he
approached forty, there was little outward indication that he
was a remarkable person.
Most Arabs at that time were pagans, who believed in many
gods. There were, however, in Mecca, a small number of
Jews and Christians; it was from them no doubt that
Muhammad first learned of a single, omnipotent God who
ruled the entire universe. When he was forty years old,
Muhammad became convinced that this one true God (Allah)
was speaking to him, and had chosen him to spread the true
faith.
No one can study the life of the Final Messenger of GOD and not have admiration and a deep respect for the man, whose legacy will be amongst us for all time.
I'm sure when you meet him in person, you'll be able to decide for yourself.
