A huge difference between conservatives and liberals in my anecdotal experience is typically conservatives are on a more steady life path to find their own success, desire to start a family, etc... and therefore a lot more to lose by throwing that out the window and doing something radical. Whereas typically liberals are loony losers with little to no future prospects in life so the hurdle to throw their life away doing something heinous like this or any of the other examples is practically already done for them.
