The reduced sentences for Ellison, Wang, and Singh make sense in light of their cooperation. This is how plea deals work. The conviction of SBF seems simple in retrospect, but when the SDNY inked these deals, they did not yet know how just easy SBF would make their case for them, with all the tampering and perjury and obstinance.

Nonetheless, we should not be fooled by a sort of "Svengali defense", where Caroline or the others claim that they were beguiled by a dark charismatic genius who forced them into the crimes. The entire inner circle is super guilty of flagrant crimes. The shorter sentences are an artifact of plea bargains, and not a sign of lesser guilt.
