Why is the result true when false is expected?

main.cpp

#include <iostream>
#include <vector>

enum ItemType
{
    TORCH,
    KEY,
    GEM,
    PEBBLE,
    GOLD
};

class Item
{
public:
    bool operator==(Item const& other) const {
        return type == other.type;
    }

    Item(ItemType) : type(type) {}

    ItemType type;
};

class Backpack
{
public:
    Backpack(ItemType type)
    {
        m_items.push_back(type);
    };

    bool hasItem(ItemType type)
    {
        for (const auto &it_type : m_items) {
            if (it_type == type)
                return true;
            else
                return false;
        }
        return false;
    }

    void addItem(ItemType type) { m_items.push_back(type); }

    std::vector<Item> m_items;

};

int main()
{
    Backpack backpack(TORCH);
    backpack.addItem(GEM);
    backpack.addItem(PEBBLE);
    backpack.addItem(KEY);

    if (backpack.hasItem(GOLD))
        std::cout << "Found.\n";
    else
        std::cout << "Not found.\n";

    return 0;
}
