It's unreasonable to blame SBF.

First, investing heavily without changing the principal is misappropriating users' funds. If a thief successfully invests with stolen principal, does that mean he's not a thief?
Second, FTX's liquidation happened during the worst market liquidity, when everyone really had no U.S. dollars, so all assets were the cheapest.
Calculating the return rate from that point, many ordinary crypto investors' multiples may not be lower than SBF's, just with smaller amounts. Even if you only bought BTC, you could have achieved up to 7x returns.
Third, SBF misappropriated not only U but also E and B, so liabilities are also increasing. Actually, similar to the second point, funds have opportunity costs. 10 billion in 2022 is worth more than 10 billion in 2026.
Still support SBF to sit in prison for life.
