For the record, I'm very much in favour of the windfall tax on bankers bonuses (along with Vince Cable, David Branchflower and Martin Wolf, just in case you think I'm being fickle. You can also have a read of this (a summary of a whole article)

From experience people who are completely obstinate (yourself) over this issue are usually absolutely and utterly clueless regarding the Economics behind such policies, the implications and only want to 'bash the rich' because they are jealous or have some petulant, militant hatred for the wealth of others which is somewhat a trifling matter.
Some of Martin Wolf's reasons to 'bash the bankers' may be fair and I can completely understand why people think they are tossers and should be punished, and maybe they should. The fact is, the populist Economics of trying to do so is rotten and flawed.
If the Government introduced a tax on footballers. The talented players would all leave and play for European clubs. Guess what, the financial sector is exactly the same.
Banks will find ways around it. The Government admitted they are only predicting the tax will raise around £500 million which is a negligible amount. It is further regulation in a market which generates
over a quarter of Britain's corporate-tax revenue, which has enabled the Government to keep taxes down for the rest of us. It encourages individuals (who are completely mobile in this sector) to simply pack their bags and move elsewhere. It discourages foreign investment, it ruins the conditions that make London a hub of international finance. It hinders the recovery of Economic growth. A long term result could be that tax revenue drops so hard the Government lose revenue and have to raise taxes on the rest of us. All this in the name of satisfying core voters and people like yourself.
So yes, Bankers are tossers, and they didn't help avoid the recession but trying to punish them is futile and Government regulation is not the answer so lets quit being jealous and worry about more important matters.
