The researcher who deals with scientific research that uses human beings must meet the ethical guidelines that guarantee the safety of the participating humans. There are several guidelines that must be applied according to the tests and the elements to which these human beings will be submitted. However, in general, we can affirm that it is the researcher's duty to request the participant's informed consent, without coercing or influencing him to give consent. In addition, the researcher must ensure that the research has a balance between risks and benefits and inform the participant of all of this. The researcher must ensure that the participant receives humane and fair treatment.

The Force Publique, who was Leopold's personal police force set in the Congo, was required to collect a right hand per successful kill. hands could've been collected by FP officers, or by the villagers themselves. Since bullets couldn't be wasted, hands were sometimes chopped off while the victim was still alive. Often times, when villages were expected to pay the different with hands, they'd attack other villages to gather hands.
At least 500 Chinese labourers were imported to work on railways in the Congo, but a majority of them either left or died.
