@Darkfinder It's quite true that they thought he was making a power play and tried to one up him so to speak. Even Cicero was skeptical of Caesar and he was about as level headed as they come. He stayed out of the conspiracy which might make one think that this was no more than an excuse. However, these were powerful and respected men in their own right. Until they acted they were for the most part beloved. Would they risk destroying a similarly beloved man in Caesar if it were not for the good of the republic?
@The_Truthwatcher alas that is but an invention. In reality the man was not even a particularly good general.
