Could Mirza Ghulam Ahmed Qadiani be a Prophet

Mirza Ghulam Qadiani did not have any scruples at using profanities to try to ridicule, intimidate, or threaten people who did not accept his false claim to prophethood. Here are a few examples of his writings:
"My enemies are dirty swine and their women are more wretched than bitches."
(Roohany Khazaen, Vol. 14, P. 53; Najmul Huda, P. 10, 53)
"All Muslims regard my books with reverence and care and benefit from their sublime thoughts except those who are the offspring of prostitutes (bastards); God has put a seal upon their hearts and they do not accept me."
(Roohany Khazaen, Vol. 5, Page 547-548; Mirat-o-Kamalat-i-Islam, P. 547; Aeena-e-Kamalat Islam, P.547-548) [Mirza Ghulam translated this Arabic word as "Bastard" in Roohany Khazaen Vol. 11, P. 282)

"The one who has no belief in our ultimate victory is fond of becoming bastard and he is bound to be product of fornication."
(Roohany Kazaen, Vol. 9, P. 31; Anwar ul Islam, P. 30)

"Are they prepared to swear? No, they'll never do so because they are liars and are derooting the corpse of falsehood like dogs."
(Supplement to Anjam-e-Atham, P. 25; Roohany Khazaen, Vol. 11, P.309)

"If Abdullah Athum is saved from death (as per Mirza's prophecy) and if all the world say the Christian was correct, then the bastard will not follow the right path."
(Roohany Khazaen, Vol. 9, P. 32)

"Abdul Haq is not content with our victories. He is itching to become a bastard."
(Anwar-ul-Islam, P. 30)

"There is nothing more foul than a pig in the world. But the ulema who oppose me are more foul than pigs."
(Anjam-i-Atham, P. 21)

"You have inflicted pain on me with your foulness. You are not truthful. I pray that you die in shame, you son of a harlot."
(Anjam-i-Atham, P. 288)

"This bastard of a doctor does not thread the straight path."
(Anwar-ul-Islam, P. 30)

He called Shaikhul Islam Saanaullah of Amristar:
"O, the son of wind, o traitor..."
(Ijaz-i-Ahmadi, P. 43/77)

The puzzling thing is that he himself wrote:
"I have never abused anyone."
(Moahiburahman, P. 18)

"He is worst who is abusive, his heart is as filthy as Latrine."
(Sar-e-Sumain, P. 74)

"Abuses and rebukes are not the acts of a believer and a believer can not be a curser."
(Azalat-ul-Auham, P. 66)

Is this how a Prophet or even a rightly guided individual would speak?
