A common excuse for carrying out a morally questionable project is, "If I don’t do it somebody else will." This rationale may be tempting for engineers who typically work in situations where someone else might be ready to replace them on a project.
Do you view it as a legitimate excuse for engaging in projects that might be unethical? In your answer, comment on the concept of responsible conduct developed in this section.

It is not a legitimate excuse for engaging in unethical projects

Explanation:

Ensuring scientific integrity and avoiding professional misconduct is a collective role of Scientists and Engineers. Every professional, engineers inclusive, must ensure they stay committed and faithful to the oath of practice they have sworn to. Engineering is an important and learned profession. As members of this profession, engineers are expected to exhibit the highest standards of honesty and integrity.  Engineers must perform under a standard of professional behavior that requires adherence to the highest principles of ethical conduct.

Every engineer must be familiar with the code of ethics of the profession, abide by it, and report erring professionals for punitive measures to be taken rather than giving excuses for carrying out an unethical project.

The concept of responsible conduct emphasizes ethical decision making, professional responsibilities, and strict adherence to professional standards and values. Every engineer and professional must take into cognizance all the responsible conducts required by their professions
