There has actually been an unverified rumor, ostensibly from Putin's inner circle, that Putin was extremely spooked by Qaddafi's eventual fate (to remind, he was tortured and raped with a stick before being shot in the stomach and slowly bled to death).

And when the massive pro-democracy protests against electoral fraud in 2011 election started 2 months later, he started to take it as a personal threat. The rumor claims that this emotional response was a significant contribution to the course change (towards more authoritarianism) that followed.
