saḥ - that person (Kaṁsa); tu - indeed; aham - I; tyakta-kāruṇyaḥ - devoid of all mercy; tyakta-jñāti-suhṛt - my relatives and friends have been rejected by me; khalaḥ - cruel; kān lokān - which planets; vai - indeed; gamiṣyāmi - shall go; brahma-hā iva - like the killer of a brāhmaṇa; mṛtaḥ śvasan - either after death or while breathing.

Being merciless and cruel, I have forsaken all my relatives and friends. Therefore, like a person who has killed a brāhmaṇa, I do not know to which planet I shall go, either after death or while breathing.
