Hello Murilo, You should always go for odd numbers. Essentially you are trying to avoid split-brain issues. Note that stopped/failed mons are basically your observations and running mons always assume that supposedly failed mons may be still running but unreachable due to a network issue. So 2 out of 4 is not a majority, it's just a potential split-brain case.
