What is the real tragedy, death or life?

Can you see the inherent contradiction? On the one hand you speak of "terrible life" in the context of 'vegetables' and on the other hand you speak of life as "tragedy" and "struggle" and seem to desire death as "peaceful state". But the life of a 'vegetables' isn't "tragedy" and "struggle" and doesn't make death appear as emergency exit, so why should it be "terrible"?

I see no inherent contradiction. I believe Sushan is presenting two extremes here, those who live in fear of death but do not live at all, and those who accept and almost encourage death. The former is sad because they could not love for fear of losing and the latter is tragic because they lost hope.
