IMHO Beast Machines Megatron was the best embodiment of G1 Megatron's motto "peace through tyranny." I found he was actually a really interesting character in his own right -- the problem was that he was also an entirely different character from Beast Wars Megatron, even though he wasn't meant to be. But if we disregard Beast Wars, BM Megatron is a fairly interesting character IMO.

BM Megatron never saw himself as a villain (unlike BW Megs who revelled in it), but as Cybertron's salvation. He saw that Cybertron was plagued with endless millenia of conflict because people had differing opinions and independent free will. By removing free will and individuality, he would thus remove disagreeing opinions, and in doing so also remove the source of conflict and thus establish peace. Of course this peace came at the cost of liberty, replacing it with an absolute brutal singular dictatorship; but it's exactly what G1 Megatron claimed to believe in, "peace through tyranny."
