Science: To Kill or to Cure

[Lombardian]

Alright Nerdfighters, next week my English class is having debates, and my topic is whether or not science has a greater capability to kill, or to cure. I'm arguing that it has the greater capability to kill (not that I necessarily agree with that, it was just the luck of the draw). I'm somewhat stuck for ideas on how to best debate this.

What do you guys think?

What im trying to say is that Although science may have good intentions now. It may not be so good later.
