The fish is what I want; the bear’s paw is also what I want. You cannot have both, and you would give up the fish and take the bear’s paw. Life is also what I want; righteousness is also what I want. You cannot have both, and you must sacrifice life for righteousness. This paragraph should be parallel.

Life is what I want, and what I want is more than life, so I don’t want to get it; death is also what I hate, and what I hate is more than the dead, so I don’t want to suffer. This is a contrast.

The fish is what I want; the bear's paw is also what I want. You cannot have both, and you would give up the fish and take the bear's paw. This is a metaphor.
