The clip Frankenstein regrets his work from Bride of Frankenstein (1935) with Colin Clive
You can go to bed now, Mary.
You'll soon be better.
I feel almost myself again.
When you're strong enough, we'll go away and forget this horrible experience.
Forget? If only I could forget.
But it's never out of my mind.
I've been cursed for delving into the mysteries of life.
Perhaps death is sacred, and I've profaned it.
For what a wonderful vision it was.
I dreamed of being the first to give to the world the secret that God is so jealous of.
The formula for life.
Think of the power to create a man.
And I did. I did it. I created a man.
And who knows? In time I could have trained him to do my will.
I could have bred a race. I might even have found the secret of eternal life.
Henry, don't say those things. Don't think them. It's blasphemous and wicked.
We are not meant to know those things.
It may be that I'm intended to know the secret of life.
It may be part of the divine plan.
No, no. It's the devil that prompts you.
It's death, not life, that is in it all and at the end of it all.
Listen, while you've been lying here, tossing in your delirium, I couldn't sleep.
And when you rave of your insane desire
to create living men from the dust of the dead,
a strange apparition has seemed to appear in the room.
It comes, a figure like Death. And each time it comes more clearly, nearer.
