Those who think that Putin is both the most repressive and aggressive Russian leader imaginable should bear in mind that this is far from the case. Lenin, for example, was fearsome. But Stalin was much worse. There may similarly come a time when the world looks at the Putin era as a time of liberality. For if the struggle by Putin to survive, and by his challengers to displace him, becomes more intense, the willingness of all to become more brutal might well increase.
In other words, be careful what you wish for.
