Other dystopian South African leaders besides Magnus Malan who could have taken power in the 80s?

Magnus Malan is always used as the leader of South Africa in an attempt to turn it into a hellhole, though I wonder if other people could be used who could have been as bad or even worse than Malan.
 
Albert hertzog. No attempts to Copt the colored and Indians. No tv. No support for muzorewa nukes against rebellious townships
 
Hertzog fought aganist tv for 10 years till 1976. He said if the hnp took power there would be an end to broadcasting except for radio and the independent homelands.
