How is Dr. Jekyll described by the various characters of "Dr. Jekyll and Mr. Hyde"?

Lanyon:

"But it is more than ten years since Henry Jekyll became too fanciful for me. He began to go wrong, wrong in mind; and though of course I continue to take an interest in him for old sake's sake, as they say...."

Utterson:

"Poor Harry Jekyll," he thought, "my mind misgives me he is in deep waters! He was wild when he was young; a long while ago to be sure; but in the law of God, there is no statute of limitations. Ay, it must be that; the ghost of some old sin, the cancer of some concealed disgrace: punishment coming, PEDE CLAUDO, years after memory has forgotten and self-love condoned the fault." And the lawyer, scared by the thought, brooded a while on his own past, groping in all the corners of memory, lest by chance some Jack-in-the-Box of an old iniquity should leap to light there. His past was fairly blameless; few men could read the rolls of their life with less apprehension; yet he was humbled to the dust by the many ill things he had done, and raised up again into a sober and fearful gratitude by the many that he had come so near to doing, yet avoided."
