Decisions that negatively affect others, but that have adhered to all the requirements of rational self-interest, have been seen to result in serious… - Melvin J. Lerner

Decisions that were rational and justifiable according to social norms nevertheless have been known to leave the decision makers troubled by negative emotional consequences. These individuals, who have gone through great pains to act ethically and responsibly, may subsequently experience entirely unanticipated feelings of guilt, shame, and anger. Logically and ethically, by society’s standards they have done nothing “wrong,” and yet they are reacting as if they suddenly discovered they are responsible for someone’s undeserved suffering.

When restoration of injustice is costly, people tend to deny injustice by blaming the victims or by minimizing their hardships and disadvantages. In this manner, BJW-based motivation merges with people's self-interest.

Our subconscious processes do not recognize the “lesser of two evils” as a justification. Evil is still evil. To that one should add that the preconscious processes may define anyone who “causes” suffering, even “rationally justified” suffering, as evil.
