As a GP? Wonderful. Asking someone else to go through life as a
Brutus? Not fair.
Maybe I'm just in a bad mood today. But the "brute" part of
Brutus is a syllable too far for me. And the assassination / betrayal angle isn't pretty either. Now, on a pet it would work very well, especially a small one for humor.
I think
Bruno is more usable than
Brutus.
All of that said, I have to say that
Marcus Junius Brutus is a fabulous combination. I'm especially drawn to
Junius (and
Junia).
