I quite agree, Safiria, one gets SO tired of this picture of the Caesars destroying an idyllic Republic when it was anything but. In fact, it was far closer to revolutions which only occur when things obviously cannot be changed within the system. But I blame Cicero for that ;) People have read his political writings literally for aeons and BELIEVED him when he described how the Republic should have worked. But as he said later, speaking of Cato, it was actually not Plato's Republic, but the "cesspit of Romulus."

It's always easier for people to understand a simple good-v-bad concept than one that is infinitely more complicated. But I think the simplest argument to make is - from the Gracchi onwards (including Livius Drusus, perhaps Catiline, the rebellion of Lepidus, the civil war, the social war, and onwards) anyone (including, of course, Caesar) who tried to make substantive reforms that hit the entrenched interests of those in power - was murdered.
