One thing I’ve noticed on this thread over the years is that left/right are used as if synonyms for good/evil.
In UK politics we tend to use left as meaning belief that state should provide a wide range of supportive services, while right means state should provide relatively few services. That is one “axis” on which a persons politics could be judged.
Another “axis” would be liberal/ authoritarian...with liberals wanting to grant individuals a high degree of freedom, authoritarians wanting to exercise a high degree of control over individual freedom.
It’s quite possible for a right wing person to be a liberal I think...I see no overpowering reason why some one who thinks state should provide few services would also believe excessive laws are necessary to control individual behaviour.
My own bias..using these definitions...is that excessive authoritarianism is more evil than being right wing.
On other hand it’s quite possible for a left winger to be authoritarian...that is how some communist states have operated.
In general I think there are dangerous left wingers...but because of way US politics has developed over the centuries the USA has relatively few of them, and many, many more dangerous right wingers.
