Why are bullets made of lead if lead is so soft?

I just saw a GIF of a lead bullet hitting a steel plate and of course the copper jacket of the bullet flowers open and the lead just kind of smushes against the plate and doesn’t do anything, why don’t we make bullets out of a stronger metal?

If a bullet passes *through* the target, is it wasted energy, less damage. Soft lead will deform into a mushroom shape, essentially splattering onto the target. This larger surface area will be harder to push through the target, meaning all the kinetic energy is transferred into the target, more damage.

For anything wearing armor, you need harder materials, to punch through the armor and damage the soft squishy targets inside, like people in a tank, or a body behind armor.
