Hi teachers,
Are these correct?

2: One who sides with the truth always dominates.
3: One who supports/sides with the truth is always dominant.

Many thanks.

2 is incorrect. The others are incomplete as standalone sentences and need context. It is possible that they would then be correct (depending on the context).

It isn’t a correct sentence. I suggest
