Today I was thinking about it again. I tried to visualize how long 20 years in my life has been. If the sentence was to start when I had just entered Madurai Kamaraj University for my masters -- before I had completed the course, before I had moved to Bangalore, before I had moved to Hyderabad, and before I had moved out of Hyderabad -- the sentence would have been almost half over by now. If the sentence were to end now, it should have started when I was in my 4th standard. 20 years in prison pretty much means you rob the convicted of his life. Well, a huge part of it. If someone commits a "crime" when he's 30, we deny him his life until he's 50. And we expect him to lead a "normal life" after that.
Looking at these laws, I can't decide if we're cruel or dumb. Maybe both.
