A little sensitive,my first note. Could you please help me to correct it?

Today, the explosions in Tanjin catch the world's attention again. Many people dies and heavy many are badly injured. I feel so sad and angry.
when the words bless ,hope are full of the social medias. I wanna ask who will be responsible for the incident?
Why are so many dangerous chemicals in that place and so near to where the people they lived?
I feel so sad about the dead firefighters. Who will be responsible for their death? Temporary workers again？
We all know who. but it means nothing.
Every time they say it is the temporary workers' responsibility. Every time we just bless send kind thoughts on social media. Wishes and hope are overused. Then, many people will forget it. It seems that forgetting is a skill of Chinese people.
Finally,we have nothing to do,but send wishes on social media.

Hello Jerry,

I was very sad to see the news of the explosions on British TV this morning, it is terrible how may have lost their lives, been injured and made homeless. I am sure that you as a Chinese person have many feelings at the moment and some of them are expressed in your post.

I can't really get the sense of the phrases below. Could you try and rephrase them?

'when the words bless ,hope are full of the social medias.'

I have made corrections to your text but some of your errors may be due to the way you are trying so hard to communicate your feelings.

My thoughts are with the Chinese at the moment.

Bob
