If a golem or an ox is intentionally made from scratch by a man via Sefer Yetzira, then for damages incurred he would be Chayav (liable) on par with one that makes a fire which causes damage. The Gemora in Bovo Kama 22a says:
- אשו משום חציו
The damages from his fire is liable under the category of his arrows thrown/launched which are human inflicted damages,
Rashi explains
משום חציו. חייבו הכתוב לאיהו קעביד דהוי כזורק חץ - The passuk makes liable one who started the fire as if he threw arrows.
So we see the liability of making a fire is due because of Directly incurring damage (he should know the fire would go out of control) as if he aimed an arrow and launched it at the article/being.
Here as well a golem or ox is like a fire because he formed it without controlling it just like a fire.
He would therefore be chayav(liable) for all 5 things with regards to nizkei adam(i.e if a person was inflicted by the golem/ox): nezek (loss of a limb) tzaar(pain) ripui(healing) sheves(work loss incapacitation) and boshes(embarrassment).
He would also be Chayav Nezek shaleim (Full damage value)if this golem/ox would inflict damage on an animal or article(tzaar ripui sheves and boshes doesn't apply to animals).
A normal ox however, the Gemoro Kesubos 41a-b concludes is Becheskas shimur -guarding itself (i.e a calm temperament). This is because it was born through the natural sequence of events which Hashem runs the world with, and though it is in the ownership of a man who should have responsibility and therefore Chayav Chatzi Nezek (see kesubos 41a), the ox is NOT "manmade" like a fire or golem/ox which he contrived from scratch. Therefore he is not chayav the 4 damages of Tzaar, Ripui, Sheves and Boshes
