Answer 2

It's actually not a necessary step for all experiments.

Step-by-step explanation:

Consent is always necessary, there's no middle ground in this. The word consent itself means: "permission for something to happen or agreement to do something."

By this definition, we can already assert that without consent, you have no permission to do whatever that you intend to do, making your action unethical, illegal, or even both.
