Overpopulation is a fiction created by oligarchic eugenicists. Many scholars and researchers have noted this fact for years. Deciding who lives or dies is an ethical quandary indeed but I disagree with your claim that every person should decide to act on their personal beliefs. Killing innocent life is wrong and should be understood as such if we are to survive as a species. Your description of the scientific community ignoring ethics in the name of progress, especially in matters such as this, alarms me but is not surprising. Those same aforementioned oligarchs fund such shadowy research for eugenics and to create genetically altered beings for their own sick purposes. It's already happening. So disturbing.
