Why should you start each paragraph with a clear topic sentence?

Because this makes it much easier for your readers to follow your line of thought. The topic sentence anchors what you are talking about. Quickly running through the opening of your paragraphs provides an overview of how you develop your idea.

Why can't relativism's claim that 'no moral judgment can be objectively - perspective independently - true' be correct?

Because it undermines itself. It is a universal claim which you could spell out fully like this: 'no one can ever under any circumstances make any true objective judgments about morality'. But this claim itself aims to be just such an objective universal claim. It wants to communicate that it is always true that a moral judgment can never be objectively true. Hence, relativism in this strong form is a self-refuting position, incoherent with its own central claim.

What is the difference between the active form 'I broke the window' and the passive 'The window got broken'?

In the first case it is obvious that I am the one who did it, while in the second the emphasis is on what happened to the window. That's why kids use the passive often when they've done some mischief.
