'soul' as an uncountable noun or a countable noun

Hi,

Would you please watch the two sentences below?

1) He has such merciful soul and he is a natural leader.

In this case, soul is ‘mind, heart’ as an uncountable noun. Actually, I think the second one is more natural. How about using ‘be’ with indefinite article ‘a’?

2) He is such a merciful soul and a natural leader.

In this case, ‘soul’ is a person with a particular mind (here, merciful heart). Among the two sentences, what’s your choice?

Thanks,
sweetpumpkin

Both sound odd; ‘merciful’ and ‘soul’ don’t collocate well. And ‘having soul’ and ‘having a soul’ are two different ideas entirely.

Thank you for the feedback. Then, how can I paraphrase them? It means he’s merciful and he’s a born-to-be leader.

He is compassionate and (a born / a natural) leader.
