That's exactly what sets rare individuals like Navalny apart: that what they believe in, what they stand for, weighs heavier than their personal well-being.
Exactly. I don't understand fascination of some westerners towards Navalny. He used to attend nazi rallies (literal sieg-heiling nazis, not "you are slightly right of Bernie"), then assumed veneer of political respectability without ever formally denouncing his previous talking points and started campaigning with the main premise of basically "I'll be better and less corrupt Czar of Russian empire". There is nothing liberal or democratic about this guy's political views.
Then again, Kasparov undermines Russia more efficiently while in exile than Navalny while inside (a prison no less). And Navalvy social media statements in exile might have been even more undermining Kasparov's.
Of course, undermining Russia with words might not help at all anyway...
"He's not even in Russia, what does he know."
I don't know why Navalny returned to Russia after being poisoned and nearly killed by Putin's thugs, but it was a very brave thing to do. It makes no sense.
Russia has always fought tyranny with literature.
Grant money that can yield all right.
I think the risk was huge (personally I thought 50-70% at the time), but not 99% or something. Also (in my opinion) people don't take into account that alternative was irrelevance in exile, just look at what happened with Kasparov's popularity inside Russia, and he was a prominent opposition activist in 2011-2012.
