I remember I fought many times with my brothers through play. Then I felt various negative emotions like sadness, madness, and jealousy. However, even though it seems harmful, it actually helps children to grow up mentally. Most of those negative experiences are forgotten as time passes, and children learn how to interact with people.
Play can be problematic only when it leaves unforgettable mental scar to a child. Fortunately I do not have any experience like that, but I imagine that if children hurt someone awfully and felt seriously guilty, or if they could not make friends and were always lonely, those memories would affect their identities very much. They might lose confidence, or, the worst thing is that they cannot love themselves through their lives.
