Answer:
The best interest is that of his country.
Step-by-step explanation:

It is germane to note that Brutus should endeavour to ensure that Caesar's interest is captured but should not be placed above that of the country since no singular person's no matter how highly placed or revered shall be greater than that of his nation's interest.
