Scientific evil is much more physical and defined. Many view scientific experiments to be very evil and wrong. For example, scientists calculate the biomass of an area by killing a small population of organisms just to find their dry mass. Many find this type of experiment is cruel and unnecessary, but scientists argue that it is the best way to calculate the dry biomass of an area. Also, there is a huge debate over testing human products on animals, such as medicine and shampoos. Scientists don't know the side effects, yet they still force the animals to take them. Some scientists may try to justify this by stating that it is a "safer" way to test products than to do so on humans, but is it not evil to make a helpless animal undergo such horrific side effects for the "safety" of humans? Along with these ethical concerns each scientist must realize as they advance in their careers, another ethical concern would be the usage of other scientist's data. We hear about plagiarism all the time, and many consider this to be very evil. To use someone's words and not give them credit where it is due is just like stealing to some and is enough for them to fire you from a job or eject you from a university. To many, these actions taken by the science world is extremely evil, but to scientists, they view things differently. They weigh the scientific benefits with their ethical values and make their own decisions as to how to proceed.
