Gene editing technology can indeed be used to modify the genes of animals to make them exhibit specific traits, including aggression. However, using gene editing technology to enhance the aggression of animals for military purposes involves complex issues at multiple levels, including ethical, legal, and technical. 1. **Ethical issues**: The use of animals for gene editing for military purposes has sparked widespread ethical controversy. Many people believe that this will cause unnecessary suffering to animals and may lead to the destruction of ecological balance. 2. **Laws and regulations**: Most countries have strict legal restrictions on biological weapons, and the use of gene-edited organisms for military purposes may violate international law, such as the Biological Weapons Convention. 3. **Technical feasibility**: Although gene editing technologies, such as CRISPR, have made significant progress, the regulation of complex traits (such as aggression) in animals remains a huge challenge. In addition, animal behavior is affected by many factors, and genes are only one of them. 4. **Unpredictable consequences**: Enhancing aggression may lead to unpredictable consequences, including impacts on ecosystems, threats to humans and other animals, etc. In general, although it may be technically feasible, the use of gene editing technology to enhance the aggressiveness of animals for military purposes is not widely accepted and carries great risks from the perspective of ethics, law, and practical effects.
