Are violent video games bad for children under 18

No, video games can't be "bad' for anyone without underlined health issues.

People enjoy playing video games. Playing them 24/7 shouldn't be done, obviously, but ii doesn't really effect you if you play for say: 1-5 hours a day.

Violent can mean lots of things, such as games like "Grand Theft Auto". It depends what you do in this game to whether it's violent or not. The point in this game is to kill, hurt and attack people, to break the law and to cause havoc. Although you don't need to do this.

Playing a violet game, then being in a bad situation decreases the risk of a heart attack in the bad situation.

Playing a non-violent game, then being in a bad situation will make you heart rate increase and 1 out of 5 you may have a heart attack. Depending on the greatness of the situation and the age of the player.

Playing violet makes you less responsive and careful. You may not help out as much.

Non-violent games won't effect that. They will keep you helpful/caring depending on the player.

These effects are not always the case. If your child is playing a violent video game and your okay with that, then don't stop them from playing it, it makes people hateful and more violent when you take something from them.

Adults face it: Gaming, TV, all of this is the voice of the future and it's going to be HUGE, okay, HUGE in years to come, bigger than it already is, children nowadays have longer fingers and better hand to eye co-ordination because of video games, internet etc. So over all, yes, and no. Just leave it. Everything will be fine.
