# Why does the person who is downvoting an answer get a downvote himself? [duplicate]

Why is that the person who downvotes an answer get a downvote himself? Isn't this unfair. I mean that the answer is not right or up to the standards so I downvote it but I also get a downvote but I never played a role in the answer. Why does this happen. Also I want to know that why was this idea introduced in the first place. This sometimes decreases your spirit of removing the answers which are not up to the mark in the fear of getting more and more downvotes
