The answer is a simile. This is because similes compare two things (these things here are his life and the dusty yards) by using like or as (specifically here as).
The other ones don't make sense: nothing is being over exaggerated (hyperbole), there are no repeating consonants (alliteration), and there are no human characteristics being given to inhuman subjects (personification).
It means that all the deaths of people get to him/her. Meaning that he/she hates all the deaths that's been happening. <span />
