Locked What is the limit of "ethical" in "ethical hacking"

[NonSensical]

At what point does someone go too far for the hacking to become unethical? 

Does finding more information than permitted to find unethical, even if it helps?

Let's see, for example you can't try to hack a server and if you find something vulnerable, notify the owner because that's not ethical. Ethical is that first you have to get an authorization from the owner of the server to be able to search for vulnerabilities.

For example, many well-known companies have reward programs for those who find vulnerabilities in their servers, these reward programs have rules of what you can and you can not do.

Really there is no limit
