Answer:
Research often raises ethical issues, especially when people are involved in the research process
In some cases, research involves vulnerable people (children, homeless people, people with disabilities, etc.)
Thus, it is of the greatest importance to follow ethical standards when conducting a research
When research is conducted in a way that contravenes ethical norms and standards, or the researchers go too far in their experiments, research is considered as unethical
The most interesting question related to unethical research is whether the results should be published and used for further research.
