Well of the 3 hatches John Locke has been in 2 have blown up or imploded... Destroyed either way... Does this seem odd to anyone else? He is the one who "believes" in the island.. He puts faith into the fact there is something great about the island.. But everytime he is in a hatch with a computer he manages to destroy any chance of learning or using the station... That just stood out to me that one again Locke feels he is doing the right thing or following his hunches and ends badly twice..
