The Bible does not mention video games, but it demands that Christians pursue purity in thought and reject violence and malice (Philippians 4:8; Galatians 5:19-21). The ethical evaluation of playing violent video games hinges on discernment, conscience, and impact. Such games become problematic if they: 1) Dull the Christian's sensitivity to real-world violence; 2) Cultivate anger, aggression, or lust in the player's heart; or 3) Consume excessive time that ought to be dedicated to spiritual growth or familial duty. While fantasy violence is distinct from real sin, the Christian is called to guard their heart and mind above all else.

The Bible does not prohibit all self-defense; it allows for the defense of life while strictly forbidding personal vengeance and retaliation. Jesus commands non-retaliation against personal insult (Matthew 5:39), but He also allowed for the practical carrying of a sword (Luke 22:36). Christian ethics distinguishes between a sinful desire for revenge and the legitimate, proportional use of force to protect innocent life (one’s own or another’s).
