Ah, a "centrist". So how much killing of people is central enough for you? How much genocide?
The idea of "radical = bad" is a trick. It's got zero to do with reality.
Example: depending on where you ask, radical means entirely different things. Read about the overtone window.
That said, radical leftism is about human rights. It is about destroying hierarchies between people. In short it means: everyone gets what they need and does what they can. Or "food, water, housing are inalienable rights."
The radical right is about superiorism. White power, discrimination and ultimately destruction of what they view as "lesser" be it people who look different, have different ancestral history etc.
And you think its smart to compromise between the two? I suggest reading books.
