1. What is it?

The notion of ‘the dangers of science’ is to question whether perceived scientific progress is actually destructive and harmful due to human nature.

In literature, the dangers of science is usually shown by science getting out of control or being misused by authorities.

Brave New World 
by Aldous Huxley

Excerpt from Chapter 2:

Turned, the babies at once fell silent, then began to crawl towards those clusters of sleek colours, those shapes so gay and brilliant on the white pages. As they approached, the sun came out of a momentary eclipse behind a cloud. Those roses flamed up as though with a sudden passion from within; a new and profound significance seemed to suffuse the shining pages of the books. From the ranks of the crawling babies came little squeals of excitement, gurgles and twittering of pleasure.
The Director rubbed his hands. ‘Excellent!’ He said. ‘It might almost have been done on purpose.’
The swiftest crawlers were already at their goal. Small hands reached out uncertainly, touched, grasped, unpetalling the transfigured roses, crumpling the illuminated pages of the books. The Director waited until all were happily busy. Then, ‘Watch carefully,’ he said. And, lifting his hand, he gave the signal.
The Head Nurse, who was standing by a switchboard at the other end of the room, pressed down a little lever.
There was a violent explosion. Shriller and ever shriller, a siren shrieked. Alarm bells maddingly sounded.
The children started, screamed; their faces were distorted with terror.
‘And now,’ the Director shouted (for the noise was deafening), ‘now we proceed to run in the lesson with a mild electric shock.’

Frankenstein 
by Mary Shelley

Excerpt from Chapter 5:

It was on a dreary night of November, that I beheld the accomplishment of my toils. With an anxiety that almost amounted to agony, I collected the instruments of life around me, that I may infuse a spark of being into the lifeless thing that lay at my feet. It was already one in the morning; the rain pattered dismally against the panes, and my candle was nearly burnt out, when, by the glimmer of the half-extinguished light, I saw the dull yellow eye of the creature open; it breathed hard, and a convulsive motion agitated its limbs.
How can I describe my emotions at this catastrophe, or how delineate the wretch whom with such infinite pains and care I had endeavoured to form? His limbs were in proportion, and I had selected his features as beautiful. Beautiful! – Great God! His yellow skin scarcely covered the work of muscles and arteries beneath; his hair was of a lustrous black, and flowing; his teeth of pearly whiteness; but these luxuriances only formed a more horrid contrast with his watery eyes, that seemed almost of the same colour as the dun-white sockets in which they were set, his shrivelled complexion and straight black lips.
