"Invictus" into Latin

As a tribute to the late N.Mandela, I’ve tried to adapt his favorite poem “Invictus” into Latin :

In his profundis jaceo
unde mundum non jam audio.
Deos de animâ laudo
per quam invictus maneo.

Quanquam crudeliter premor,
non gemo, nec unquam fleo.
Me utantur sicut reo,
frangi possum, sed non flector.

Ultra istum irae locum,
horror tenebrarum latet.
Tametsi senectus patet,
hanc semper habeo jocum.

In me adest nullus pavor,
ante angustias non tremo.
Fatum meum summo rego,
animae sum imperator.

This English poem had a Latin title, so it seemed obvious it ought to be rendered into Latin…
