Absolutely. Children look at other people as role models. If they see someone doing something they would copy. As you know alot of kids love video games and if such games like GTA or shooting games that have swearing in them, could lead them into copying them. Such as whenever a kid gets in trouble he says "SH!T" or something else. I absolutely think it has an negative impact on younger children as they are learning to swear and learn about sex and turn their minds into dirty ones...
