I'm playing my first pokemon game, which is pokemon white on the nintendo dsi and wondered if it would be dumb pass through some wild pokemon instead of catching them.

You don't need to catch every Pokemon, but it's just smart to catch them all to develop as many strategies as possible. Besides, the whole point of Pokemon is to "Catch them all". I would focus on completing the National Pokedex, which is a little over 200, but not the international, which is like 600.
It's always a good idea because I believe you can receive a shiny Deino or Axew upon encountering them all/catching them all/completing Pokédex. If you don't want all here are some good Pokemon in Pokemon White:
Larvesta->volcarona
Drillbur->Excadrill
Deino->Zweilios->Hydreigon
Litwick->Lampent->Chandelure
Axew->Fraxure->Haxorus
Hope this helps!
