It's the same as when individuals say, I felt frustrated about him. You are endeavoring to share the feeling that you think the other individual is feeling. For this situation the essayist thought the man was so miserable and "loaded with feeling" that it influenced him heart to wiped out. It doesn't really imply that he is physically unwell, despite the fact that that could be the situation.
Hey there
Being the bolded verb loved, it is conjugated in the in the preterite of the indicative mood.
The indicative is the mood of the real life; it makes a statement or asks a question, and the preterite is the time of actions that already happened. In this case, the verb is showing something that happened in real life, real feelings and in the past.
Hope this helps
