People need to realize you can control the feeding

Most deaths come from fighting when your behind from my experience and there is always a way to play safe. If your behind your gonna lose cs regardless their is no point in giving the enemy more gold by continously trying to fight. Thats where the jungles comes in but you cant really blame them when you constantly leave yourself open to giving easy kills to the enemy champion. I feel like some people are just too proud too play safe and gamble with not only their own lane but the mid to end game result. Can anyone else shed light on this because I try to explain this when I play with friends
