The Mad Scientist

        The film Poison features a science experiment gone wrong, turning the scientist, Dr. Graves, into a leper. The scientist then uses his condition to his advantage and starts infecting people, resulting in their death. This concept of science experiment gone wrong is still seen in today's pop-culture. Some use their new-found abilities for good, and some for bad. Since Dr. Graves used his condition for bad, we'll take a look at some Super Villains who also acquired their powers through science and used their powers for evil.

Reverse Flash: Eobard Thawne aka Reverse Flash, was born in the future and grew up being the Flash's number one fan. As an adult he goes on to replicate the electrochemical bath that gave Barry Allen (The Flash) his super speed as well as undergoing surgery to make himself look like the Flash. Thawne then becomes mentally unstable upon discovering that he is destined to become the Flash's villain. Upon realizing this, Thawne travels back in time with the sole purpose of tormenting the Flash at different points throughout his history. Though he is unable to kill the Flash (because without the Flash having existed, he too wouldn't exist as the Reverse Flash) he still manages to torture him mercilessly; for example, attempting to kill his wife.

The Lizard: Curt Connors aka The Lizard, whom famously appears in the Spider-Man comics,  was a genetic biologist who researched the ability of certain reptiles to regrow missing limbs, partially to find a way to regenerate his right arm that he lost during a blast in a war in which he was a doctor helping the wounded G.I's. He successfully regenerated the missing limb of a rabbit and then chose to test it on himself. It resulted in him transforming into a violent lizard monster. Although he is still able to revert to his human form, he suffers occasional fits of his alter ego breaking free, due to stress or chemical reactions (situations vary).  When the Lizard takes hold of the body, one of his objectives is to kill Curt Connors' son. 

       The theme of science gone wrong has been a popular theme for centuries, and these three characters whose present states were altered by a science experiment all went out and intentionally sought to kill people. They are all outsiders in society, making all three of them Queers that Kill.
