US intervention, as in Chile, should be primarily to benefit US interests, not merely to oppose socialism in principle (though it is in principle an evil, imo). But as far as within the country itself I don't see how you can blame the Right - and more to the point property owners - from trying to defend themselves against 'democratic' expropriation by whatever means necessary. In this extremity one is lucky to have a Pinochet to turn to. The thought that the majority of the 'people' voted to rob you of your property is no comfort at all - you will still fight for it if you can, including by a forcible coup, removing the socialist regime if possible.
Actually I still feel this way - everyone should fight for their own interests. However I have learned to look at things from the other fellow's point of view - the working class should also fight for their own interests - socialism.
Personally my new ideal is a (preferably) bloodless compromise between the interests of the owner, and the interests of the worker - in other words liberalism/social democracy, the political ideology of moderation and balance.
