Probably more then you.
Past is past, present is present.
He was "appointed" by Yeltsin to keep status quo as far as Yeltsin and his family was concerned, and he did his part - and even built Yeltsin Center in my city for 8 billion roubles (around 200-300 millions $ at the time it was built).
And he also happened to be quite decent administrator who did think about what is good for the country after getting his loyal associates cushy positions in government companies - both to reward loyalty and to control them toward filling Russian budget and fulfilling social obligations. Sadly, no better candidate exist, and it is unlikely that Russian political system will produce one unless forced to by other circumstances.
But this has little to do with unproven accusations against him. No connection have been ever shown between killing and Putin (other then "because who else would want to???" and "KGB!!!"), no billions were ever directly connected to him too to prove his corruption.
