Why do we react to bitter taste the way we do, and how did we acquire this function during our evolution as a species?

Could it be that a strong bitter taste is predominantly associated with poisonous or toxic plants and our dislike of bitterness is an evolutionary mechanism to ensure survival?

Not so sure about this specific aspect, as it might be pure speculation, but could preference for bitter taste indicate [latent or suppressed] suicidal tendencies?
