[Avodah] Moshe and aharon

[Rich, Joel via Avodah]

Rashi (Bamidbar 27:13) states that the Torah’s continual pointing to Moshe’s and Aaron’s punishment (an earlier demise) for not being mkadish sheim shamayim (sanctifying HKB”H’s name) was at Moshe’s request so that no one think they were punished for not being believers but rather the lack of Kiddush hashem was their only sin. Rashi compares it to ( see Yoma 86b ) two sinners being lashed, one for adultery and one for eating unripened shivit fruits.[the exact nature of the sins and lashes is subject to debate]
Two questions: (1) How does this analogy (or the statement of sin) ensure that repetition would communicate that this was their only sin? (2) If the punishment for two sins is equal, why is one considered worse
