Hi there,
Hell is the realm of suffering existence:
Those people who kill other people will go to hell; Those who disturb other people peace of mind all the time, they will to hell. Those who kill their parents, they will go to hell. Those people who detroy the life of wholesome people, they will go to hell. However, it is not an eternal hell.
Check the explanation of 31 planes of existence... you may find out what hell mean.

You will see the meaning of hell, it may not be a place that god punish someone; but a place those people who live the life full of hatred and unwholesome actions (destroy life, disturb other, killing, robbing, and etc..) will descend into it by the weight of their unwholesome deeds.
Best Regards;
Johnny
