Ancient Pagans
As soon as Christianity was legal (315), more and more pagan temples were destroyed by Christian mob. Pagan priests were killed.
Between 315 and 6th century thousands of pagan believers were slain.
Examples of destroyed Temples: the Sanctuary of Aesculap in Aegaea, the Temple of Aphrodite in Golgatha, Aphaka in Lebanon, the Heliopolis.
Christian priests such as Mark of Arethusa or Cyrill of Heliopolis were famous as "temple destroyer." [DA468]
Pagan services became punishable by death in 356. [DA468]
Christian Emperor Theodosius (408-450) even had children executed, because they had been playing with remains of pagan statues. [DA469]

16th and 17th century Ireland. English troops "pacified and civilized" Ireland, where only Gaelic "wild Irish", "unreasonable beasts lived without any knowledge of God or good manners, in common of their goods, cattle, women, children and every other thing." One of the more successful soldiers, a certain Humphrey Gilbert, half-brother of Sir Walter Raleigh, ordered that "the heddes of all those (of what sort soever thei were) which were killed in the daie, should be cutte off from their bodies... and should bee laied on the ground by eche side of the waie", which effort to civilize the Irish indeed caused "greate terrour to the people when thei sawe the heddes of their dedde fathers, brothers, children, kinsfolke, and freinds on the grounde".
Tens of thousands of Gaelic Irish fell victim to the carnage. [SH99, 225]

Here the Christians "did no other harm to the women found in [the enemy's] tents—save that they ran their lances through their bellies," according to Christian chronicler Fulcher of Chartres. [EC60]
Marra (Maraat an-numan) 12/11/98 thousands killed. Because of the subsequent famine "the already stinking corpses of the enemies were eaten by the Christians" said chronicler Albert Aquensis. [WW36]
Jerusalem conquered 7/15/1099 more than 60,000 victims (jewish, muslim, men, women, children). [WW37-40]
(In the words of one witness: "there [in front of Solomon's temple] was such a carnage that our people were wading ankle-deep in the blood of our foes", and after that "happily and crying for joy our people marched to our Saviour's tomb, to honour it and to pay off our debt of gratitude")
The Archbishop of Tyre, eye-witness, wrote: "It was impossible to look upon the vast numbers of the slain without horror; everywhere lay fragments of human bodies, and the very ground was covered with the blood of the slain. It was not alone the spectacle of headless bodies and mutilated limbs strewn in all directions that roused the horror of all who looked upon them. Still more dreadful was it to gaze upon the victors themselves, dripping with blood from head to foot, an ominous sight which brought terror to all who met them. It is reported that within the Temple enclosure alone about ten thousand infidels perished." [TG79]

Heretics
Already in 385 C.E. the first Christians, the Spanish Priscillianus and six followers, were beheaded for heresy in Trier/Germany [DO26]
Manichaean heresy: a crypto-Christian sect decent enough to practice birth control (and thus not as irresponsible as faithful Catholics) was exterminated in huge campaigns all over the Roman empire between 372 C.E. and 444 C.E. Numerous thousands of victims. [NC]
Albigensians: the first Crusade intended to slay other Christians. [DO29]

Estimated one million victims (cathar heresy alone), [WW183]
Other heresies: Waldensians, Paulikians, Runcarians, Josephites, and many others. Most of these sects exterminated, (I believe some Waldensians live today, yet they had to endure 600 years of persecution) I estimate at least hundred thousand victims (including the Spanish inquisition but excluding victims in the New World).
Spanish Inquisitor Torquemada alone allegedly responsible for 10,220 burnings. [DO28]
