Whether a person can marry someone who kills animals and people is a complex and deeply personal question. It depends on individual values, beliefs, and moral principles. Some people might find it extremely difficult or impossible to be in a relationship with someone who engages in violent or harmful behavior, including killing animals or people.
Marriage is a significant commitment that involves sharing life, values, and goals with another person. It's crucial for individuals to consider their own values and what they are willing to accept in a partner. Acts of violence and harm towards animals and people can be indicative of severe issues that may pose risks to the well-being and safety of the person in the relationship and others around them.
Ultimately, each person must make their own decision based on their own values, feelings, and circumstances. However, it's essential to prioritize personal safety, emotional well-being, and moral values when considering a life partner. If someone is concerned about a partner's behavior, seeking guidance from a trusted friend, family member, or professional counselor may be beneficial.
