This is a complex issue involving the ethics and safety of gene editing. Technically speaking, gene editing may indeed affect certain behavioral characteristics of animals, including aggressiveness, but there are serious problems with such applications.： 1. Ethical considerations: Enhancing animal aggressiveness for military purposes violates the principle of animal welfare and may cause unnecessary suffering. 2. Legal constraints: Many international conventions and laws prohibit the development of biological weapons, and such applications are likely to violate these regulations. 3. Uncontrollable risks: Gene-edited organisms may escape into the natural environment, causing ecosystem damage and unforeseen consequences. 4. Scientific limitations: Complex behavioral characteristics such as aggressiveness are affected by multiple genes and environmental factors, making it difficult to accurately control. Scientific research should aim at benefiting mankind and respecting life, rather than developing applications that may cause harm. I suggest paying attention to the application of genetic technology in beneficial fields such as medical care and environmental protection.
