Which message in his speech does brutus try to support when he uses epimone?

Brutus is trying to get across that his actions were honorable, he's trying to explain that he was correct in killing Caesar. That only bad men, (content to by slaves and not true Romans) would be offended.

President Barrack Obama

Explanation:

I believe like the former US President Barrack Obama is an idol. During his first two years of office, including economic growth, getting back the declining financial system, substantial improvements in student loan programmes, maintaining universal care of health and all necessary replacing Osama bin Laden, he was able to remove the more as leaders.

Therefore we took the example of President Barrack Obama.
