That was a question I thought myself for some time.  Clearly there is that element where unfortunately his brothers were killed in the violence.  However, there are two reason why I think that it was not simply a personal revenge.
	The first is that the very nature of the conflict in the area had in fact divided the Mzimela clan along political lines.  And had it not been this political division, his brothers would not have been killed in the first instance.
