Is it considered the one who uses bots as a thief? Very little ethical, yes, but they are the rules, I think RBF is poorly implemented, it should be an irrevocable choice of those who send the funds and not depend on the configuration of each node.
I don't know. But I know that I will send at least 45% to the winner address if my bot succeeds. I guess THAT will be enough to prevent the winner from having a heart attack due to losing everything.
