[Solved] How to cancel out all damage except for SUICIDE

So I want to just cancel out ALL the damage except for doing /kill
Here is my code:

Code (Text):

    @EventHandler
    public void Damage(EntityDamageEvent e) {
        if (e.getEntity() instanceof Player) {
            if (e.getCause() != DamageCause.SUICIDE) {
                e.setCancelled(true);
            }
        }
    }

But it it does not do that, it still cancels out /kill, how do I fix this?

 

Thanks!
