Giving compliments is not necessarily egotistical. Neither is criticism necessarily of the mind. Learning to speak with consciousness and to help humanity does not fall into specific checklists of "to do" and "not to do," for one must learn to speak when necessary, and to be silent when necessary. There must be balance. This is an intuitive process in which we learn to irradiate love, even if it be hard or sweet, even if the ego of another person reacts, or if they feel elevated by our compassion.
Remember that the Law is Mercy (Chesed) and Severity (Geburah), balanced through Splendor (Tiphereth). What Nietzsche was against is false Christian piety (Mercy without the Law, without Justice, which is complacency with crime). He spoke in favor of Geburah, guided by the Spirit, as he mentions countless times throughout that text.
Joyful in hope, suffering in tribulation, be thou constant in thy prayer.
Benedictis, qui venit in nomine Domini. Osanna in excelsis.
"Blessed is he who comes in the name of the Lord. Hosanna in the highest!"
