You know the answer to that question. Except Brown got out of the wool business in 1849 when he had his partner Perkins went out of business. Brown had a much long history in the tanning industry prior to his association with dealing in wool.
Your unstated premise that Brown tried to forment slave rebellion to bolster the price of wool is a very far reach.
It isn't the only aspect of it. My point is also along the lines of him developing a hatred of the cotton producers as a consequence of bitter disappointment in his efforts to make a living in the wool business.
That hatred colored his outlook, and he post hoc justified that hatred by claiming a noble goal for it.
I think i've mentioned to you before, that too often people's "morality" is colored by their own self interest. Here is what I consider to be a fairly clear example of it.
