So, by your earlier definition of Hell being a place where those who make life miserable for others are are sent, then, does that mean you don't feel that Anne Frank, for example, went to Hell?
The difficulty I see here is, you are setting a definition on what it means to be Christian to yourself.
Your Bible states that the only way to the Christian heaven is though Christ.
This drives up many problems, since many Christians (of course, according to you, not true Christians) have done many bad things which have encouraged others to not follow Christ.
Still others like myself who see the cherry picking that goes on as a person justifies their own belief, and decide to just dump the whole thing.
