I have fat-fingered before but this is crazy.
Unintentional obviously.

A presumed panic-induced error
The transaction has signs of a panic-induced error, with the user sending a subsequent transaction fast to prevent the original transaction from being included in a block and becoming final. Jain suggested some potential explanations:
“Maybe he meant to use 30.5692 sat but, due to haste or butter fingers, ended up using 305,692 sat.“
The second RBF transaction also added an additional input unspent transaction output (UTXO). This UTXO contained nearly 0.75 Bitcoin (BTC). The change was mistakenly included as part of the fee, likely because the user failed to update the change address or misjudged the transaction’s structure.
Another possibility raised by Jain is that the user got confused between a fee in absolute terms and one set in satoshi per virtual byte (transaction size) or that the automated script behind the transaction contained a bug. The wallet could allow setting a fee in satoshis, which could lead to a scenario where the fee is set way too low, a warning about the low fee and an overcorrection:
“System reads it as 30 sats total fee, which is way too low, so user types 305000 thinking it means 30.5 sat/vB, and the wallet actually applies 305,000 sats/vB, which is insane.“
