No... you're not a bad person. Warrens relative did something bad... something VERY bad. OK... sometimes people get messed up in drugs, or alcohol for that matter, and hopefully there's someone who's strong enough to get to the "real" person, and drag them away from it... But no matter how you look at it... he did something VERY bad...

Since he's off drugs now, I'm sure he will pay for what he did for the rest of his life... maybe not in jail, but in his thoughts and dreams... if he doesn't, then he's not a very nice person... if he does pay, than maybe that is punishment enough... No matter how long he stays in jail, no matter how he feels, that woman will not be able to cuddle her kids, or see them grow up. She didn't get the chance to get off her drugs, and impove... but Warrens relative does! Hopefully he'll accept which ever time he'll recieve, and use his life for good.

You're a good person, thinking of the life that was lost... let's just hope Warrens relative does the same!
