Pluto is lots of things, but He generally is not associated just with Death. Actually death charts have a lot more Saturn in them than Pluto, since Pluto usually represents once a life time change that results in re-birth and regeneration.
IMO, you need to explore more of astrology, and to do that you will need to purchase some books. I would reccommend these for beginners:
For solid nuts & bolts, no mythologies, no frills:*
Astrologer's Handbook, by Sakoian and Acker.
********For a dang good read:* Secrets from a Stargazer's Notebook, by Debbi Kempton-Smith, but note she lacks aspects.
********The best hand-holding:* Astrology for Dummies by Rae Orion (pen name of Nancy Hathaway).*
********The first three volumes of the March & McEvers are good, but they were designed for classroom work, in other words, for people who are organized and determined.
