[Terminator] Do terminators feel a sense of vindictiveness?

So we see in T2 that advanced terminators learn and can actually develop "feelings" of a sort. Obviously that particular T-800 was probably the first to ever feel a sense of love or attachment. But in the very first Terminator movie, we see an example of a terminator doing something that I can only describe as "vindictive". In Kyle Reese's flashback, we see an infiltrator terminator unsuccessfully try to sneak past security because of the guard dogs that humans keep to detect infiltrator units. A gunfight ensues, there's a back and forth, and during one of the moments when the infiltrator has gained the upper hand, he deliberately turns his weapon on the captive dogs and guns them down. 

Why do this, if not out of pure vindictiveness? Humans with advanced weaponry have a difficult time taking down T-800s, so dogs, even if they were off chain, are virtually no threat at all. The jig is already up and the soldiers all already know there's a terminator in their base. So it's not like killing the dogs would serve any further purpose for infiltration. Terminators are machines, so it's not like the dogs barking would really distract it in any way. And because terminators are machines, they operate on logic. Obviously a cold brutal logic, but logic nonetheless. Terminators are efficient, not bloodthirsty. Even during the brutal police station shootout, the Terminator walked right past plenty of cops and didn't kill them unless they made themselves enough of a nuisance. 

After going through all the possible scenarios, I can only come to the conclusion that that particular terminator had been operating long enough to develop emotions, and one of the emotions it developed was vindictiveness. Which has absolutely terrifying implications.

The dogs can tell a terminator from a human. If those dogs end up in the hands of other humans, they can reveal the terminator’s presence.

Primary objective: eliminate the enemy. 

Secondary objective: reduce the enemy’s capacity to wage war.
