PlayerInteract goes beyond return statement

So, I've got this (it got pretty messy after my tries of debugging, sorry about that):

Code:java

@EventHandler
    public void onPlayerInteract(PlayerInteractEvent e) {
 
        Player p = e.getPlayer();
 
        if (p.getItemInHand().equals(null)) {
            p.sendMessage("return");
            e.setCancelled(true);
            return;
        }
 
        ItemStack it = e.getItem();
 
        if (it.getItemMeta().getDisplayName().equals(ChatColor.RED + "" + ChatColor.BOLD + "Bandaz")) {
 
            p.sendMessage("jest bandaz");
 
            if (e.getAction().equals(Action.RIGHT_CLICK_AIR) || e.getAction().equals(Action.RIGHT_CLICK_BLOCK)) {
 
                p.sendMessage("jest right-click");
 
                p.setHealth(p.getHealth() + (p.getMaxHealth()*0.5));
                p.sendMessage(ChatColor.GREEN + " Uzyto " + ChatColor.DARK_RED + "Bandazu" + ChatColor.GREEN + ".");
 
                p.getInventory().remove(p.getItemInHand());
 
            } else {
                return;
            }
        } else {
            return;
        }
    }

So, I've specified that I want it to return if player's hand is empty on interact. But it throws exception in console, referring to the line with specified item. How should I fix this?
