The individual who is responsible for inserting the needle could be pricked by the needle and become infected and criminals are still people.  It is only moral to do this for them.

I consider the great invention for mankind is the writing and more specifically the alphabet!\nThe inventor of the alphabet was living on the island Crete, south of Athens, north of Egypt, some 4,000 years ago!

Yes, it was Konrad Gesner.\n\nIt dates (we think) to 1565, when Konrad von Gesner, a Swiss-German naturalist, devised a wooden container filled with graphite for the purpose of drawing and writing. Refined, the invention—arguably history's most practically useful communication tool—became universally popular. If you keep a sharpener handy and can avoid breaking the point, you ostensibly can get about 45,000 words or 35 miles of sketched lines from the average pencil.\n\nIncidentally, the common term "lead pencil" is misleading (please excuse the play on spellings). At one time, graphite wrongly was considered to be synonymous with lead.

There are several diseases one can get from doing what you did, not the least of which is AIDS or Hepatitis B or C, depending on how sterile the needle was and who used it for what. You need to see a doctor.

No, Hippocrates was the Greek most famous for his work on medicinal practices. Many of his ideas were off base: however, his Hippocratic Oath (you know the one, "First do no harm", etc.) is still pledged today. Credit given for first envisioning something similar to a helocopter is usually given to Leonardo da Vinci. He worked for the Medici family, and part of his job was to create military defensive ideas.
