Self interest is not evil. Taking away people's incentive to win is evil!
Self interest is often conflated to be greed which is then seen as evil. I find no difficulty in identifying greed as evil. What I do find difficult is to separate honest and reasonable self interest that is survival oriented for both the individual and society from greed which is not survival oriented.
Perhaps the best way to define greed is as a hunger that cannot be sated and that grows greater the more it is fed. In extreme cases this sort of hunger destroys not only the individual but the society of which he is a part.
Taking away a person’s incentive to win is evil because this is an abrogation of his self interest which as I noted above is good not only for himself but for everyone around him.
