What is the difference between comparative and superlative adjectives?

A comparative adjective compares exactly two things, such as bigger. A superlative adjective compares one thing with a whole group of three or more, such as the biggest. Superlatives always need the before them, while comparatives usually do not need it at all.

Why do some adjectives use the most instead of -est?

Do superlatives always need the?

Yes. A superlative always needs the before it, such as the biggest or the most dangerous, even when the group being compared is not named directly.

How do I know if an adjective needs -est or the most?

Short adjectives, usually one syllable, add -est, such as tallest. Longer adjectives, usually two syllables or more, use the most instead, such as the most dangerous.
