It sounds like your sister had good intentions as many family members do, sort of the 'starting a new' concept but with someone with dementia they need familiar or on-going supervision to ensure they feel safe.
It is difficult for some folks with dementia to articulate their needs or wants and if he thinks he is not home, missing his spouse, etc that could be misunderstood as anger or aggressive behavior. Keep that in mind.
All in all, if a person with dementia is being cared for well, those around them are happy and confident they too will often follow suite. Positivity can be contagious.
